N_Cook <diverse@tcp.co.uk>: Sep 30 09:16AM +0100 Will not reliably switch or stay latched in piano or synth mode via the select switch. I suspect the light action switch is too light. Easy enough to remove the keycover and inspect the phosphor bronze action. Is it just a matter of cutting back the spine of the keycap a bit , so the action is farther removed from a hair-trigger situation? All clean and tidy inside the switch.

N_Cook <diverse@tcp.co.uk>: Sep 30 04:14PM +0100 I think cause or part of the problem is the metal casing of the top , containing the switches, has been bent,dished or flexed slightly. The keycaps are then partially compressed by the metalwork. Some padding washers will go in there, as any of the keycaps could be the next affected. Also the wooden end cheeks are loose. Only 2 thin wood screws per cheek , and the wood is now not holding the screw threads. Some bracing plates will go in there with 3 woodscrews extra. Employing the old carpenter's trick of the axis of the 3 screws all angled relative to each other so they mutually anchor themselves in there, also allows longer screws for the relatively thin wood available.

Bill Martin <wwm@wwmartin.net>: Sep 29 09:24PM -0700 Hi, Anyone have a list of "usual suspects" with this HP1740A scope when there is no display at all? Front panel lights seem working, but that is all I find so far. Have not opened the case yet, nothing seems to "smell bad" so far. I won't be stressed if it can't be fixed, I bought it for the nice rolling stand it was sitting on...I have another similar, slightly newer antique scope that is still working that can use that stand.   TIA, Bill M

Also the vertical output chip fails so you will get a trace but no deflection. If you can go over all the joints carefully you might have an easy repair.

It says it can affect 2.5% of the population. I have never heard if it. Surely if it affects that much of the population, I have probably met many people with the condition.   When you first said it, it seemed like it would be a pretty seriously debilitating, but after thinking about it probably not so much.   I would guess you also have close friends and co workers that you can distinguish their faces?

Phil Allison <pallison49@gmail.com>: Sep 30 03:20AM -0700 ** Hi all,   one thing repair techs dread is being presented with an item for repair that cannot be put under test while in the workshop. Usually, this is because the item requires a missing accessory in order to operate OR is itself an accessory to a larger unit.   Essential accessories could be AC adaptors or multi-voltage PSUs for mixing consoles, IR remotes, power leads with oddball plugs, foot switch units with multi-pin connectors and many others.   A real annoyance is when radio mics arrive with no receiver, or the reverse.   Some customers seem unable to comprehend that repairing electronics involves a LOT of testing - not just final testing ( which they fondly imagine they can do for you) but also initial and continual testing during fault finding and fixing process.   Dunno if Scotty ever said the words in my heading, but he should have - it would make explaining it a lot easier.       ...

The switches are that membrane type where a conductive bit of carbon shorts two contacts together. They can be pried open by drilling into the case a bit with a Dremel tool. It looks like over the years the metal contacts had formed a layer of oxidation, preventing a good contact from being made.   Replacing the 4011 stopped the oscillation.

John-Del <ohger1s@aol.com>: Sep 29 02:54PM -0700 > get the new firmware then they get to sue. If not then they would get > no compensation because they have not suffered a loss. > ERS   Owners will NOT have the option to opt out of the firmware being upgraded because the cars are not EPA certifiable at this point. They need to be brought into compliance by U.S. law or be crushed if they cant. If the owner refuses to get an approved fix done, then many (if not most) will fail the car's emissions test and pull the reg (CT).   As far as suffering loss, that depends on the fix. If the firmware (and most likely hardware) changes do bring the cars into compliance, but causes a loss of performance and/or fuel mileage, then the owners have indeed suffered a compensable loss. If it can be shown that the resale of the cars suffered as a result of all of this, then that's also compensable. If the fix actually improves performance and efficiency (long shot but who knows?), then it's a win for the customer as long as the fix doesn't shorten the life of the engine.   If the fix ends up being like so many other recalls, I'm sure VW will also include some VW swag for the customers to compensate for the trouble (VW backpack, key rings, VW feminine hygiene products, etc.) and probably coupons for service and/or extending the warranty.   It will be interesting to see if VW had a fix ready in case the scam became known.

The first teacher he showed it to said that it looked like a bomb and to put it away and not show it to anyone else. The kid took it to another teacher and plugged it in the wall so it would alarm during class. He was questioned by teachers and by the police about whether he brought the clock in to make it look like a pretend bomb, which is still a crime. https://www.youtube.com/watch?v=pzUtR5TvuzQ   Here is the mayor saying that law enforcement and "numerous" teachers are receiving death threats over the incident.

Common mode choke L10-L12 had apparently burned and shorted, so I've temporarily replaced it with jumpers.   The +7 and +5 rails are up and running now, but the 3.3 volt rail is still down. I measure about 8.6 volts from positive to negative across C109, but I'm also seeing about 8.7 volts from the ground terminal of C109 to the ground fin of regulator IC7.

I believe it's accurate, I was just being dumb. The common mode choke was just 2 windings - it was scorched and shorted. I cannot find L13 anywhere on the board. Still, there seems to be a continuity problem somewhere as the buck switcher is not getting an appropriate input voltage.   I think I'm first going to take the other poster's suggestion, disconnect the switcher completely and see if I can get the logic working off a bench supply, as if I can't get it operating that way then this exercise is really for nothing.

N_Cook <diverse@tcp.co.uk>: Sep 29 10:39AM +0100 Unusual package, I can get hold of the usual 1.25mm pin spacing SMD 8 pin SOIC IC . I might be able to find an exact replacement if I knew the SMD style code for .75mm spacing, normal width of SOIC IC body but not so long. May be about .75mm pitch , not exactly .75, only ruler measurement. At a pinch I might be able to twist 90 degree each pin axially and realign for the smaller pitch, and/or grind back the pin width with .5mm dremmel discs, but very constrained space and an exact replacement would be a lot easier.

N_Cook <diverse@tcp.co.uk>: Sep 29 11:26AM +0100 Oddly its wider than normal SOIC. Tried grinding and bending pins of a practise 8pin SOIC and that will work, but I'd like to obtain a proper footprint replacement, if anyone knows the style, something like QSOP.

N_Cook <diverse@tcp.co.uk>: Sep 29 11:36AM +0100 perhaps TSOP type II, .8mm pitch.

Smarty <nobody@nobody.com>: Sep 29 05:18AM > He was asking questions about using his Apple computer for video > editing. > That doesn't really add up to me.   Blindness is not a binary condition. There are a wide range of deficits including a somewhat arbitrary "legally blnd" state which differs from one country to another. There are those whose blindness may be principally in color perception, night time vision, peripheral vision, etc.   The bottom line is that video editing and many other tasks which rely on vision can be performed by those individuals whose medical and / or legal situation is accurately described as blind.

The EPA has a LOT more power than the NHYSA does. They will simply blacklist the VIN numbers of all the vehicles that are not in compliance with the regulations.   Owners will probably get a letter telling them that they have XXX days to get to a dealer and have the fix done. If they don't they will get a letter from the Feds telling them that they are driving a non-compliant vehicle and that the registration has been suspended.     -- Steve W.

It seems CA has portable roadside emissions checkpoints that measure the emissions as you drive. I wonder why they haven't seen a major problem with VW vehicles as they pass these checkpoints?   Maybe it is a minimum difference between a properly working system and a VW in the fuel economy mode? Like someone else said - is the nominal emission near zero and 10 to 40 times worse is still an extremely small amount of NOx.

I understand what you are saying but in this case that isn't it. I did look at the connectors actually and they are that blue plastic. I KNOW that blue plastic is not stronger or better due to its color but I think they have a tendency to only use that color for really good plastic. Thaat is really only an impression I got, but it is based on real world observations.   At any rate, I looked at them pretty good and they are not splitting. And the fact that the new fault came after I sliped with the probe, that ain't it, at least right now.   >"Of course clean the PCB edge connectors, etc... "   Been wiping the edge down with LPS2 which is really fantastic. Never ever becomes conductive and really does the job better than I thought it should. Someone showed it to me about 35+ years ago and I have been sold ever since. I have never ever used Deoxit, I simply have no need for it.

That worries me because them fuckers could make it so the SMPS will never get drive again unless you buy tool J-1120953A.   The file I already had indicates no real hard fuzibles that would go. And I have physically looked. I will look again. I really want an easy solution, like some little one ohm resistor or some shit. It should not be that hard, it was a simple short circuit.   Who knows, this may totally overshadow the vertical sweep problem. But this is not something I can just st aside.

Phil Hobbs <pcdhSpamMeSenseless@electrooptical.net>: Sep 28 10:42AM -0400 Hi, all,   I have one of these nice lead salt vidicon cameras, good from about 700-1900 nm, but it's on the fritz with a blank image. Fiddling with the +300V adjust pot will make the image appear for a few tenths of a second, so it looks like the tube's fine and there's some resistor that's out of spec and offsetting the bias someplace.   All the power supplies look fine--apart from the +300, they're all 78xx/79xx regulators, so it's easy to check. I have the user manual, which talks briefly about all the adjustment pots, but after going through their abbreviated procedure, it's still flatline.   It's all through-hole, so I can probably do OK without a schematic, but before I spend a day on it, does anybody have a lead on a schematic? (It's the 7290, not the 7290A.)   Sofradir (formerly Electrophysics) hasn't responded to my query.   Thanks   Phil Hobbs   -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC Optics, Electro-optics, Photonics, Analog Electronics   160 North State Road #203 Briarcliff Manor NY 10510   hobbs at electrooptical dot net http://electrooptical.net

I think the update should come with a hundred dollar check and a 2L bottle of Coke - diet or regular as a jester of goodwill. ;)   OTOH, my guess is that a lot of folks will just ignore any fix, if they can avoid it. The big question is will they be compelled by the state or feds to do this or will this be be treated as just another recall.

bv4bv4bv4@gmail.com: Sep 27 12:20PM -0700 The Miracle of Iron       Description: The Quran seems to imply that the iron was something "sent down" and not from this earth, an idea not foreign to 20th century science.   Iron is one of the elements highlighted in the Quran. In the chapter known Al-Hadeed, meaning Iron, we are informed:   "And We also sent down iron in which there lies great force and which has many uses for mankind..." (Quran 57:25)   The word "anzalna," translated as "sent down" and used for iron in the verse, could be thought of having a metaphorical meaning to explain that iron has been given to benefit people. But, when we take into consideration the literal meaning of the word, which is, "being physically sent down from the sky, as this word usage had not been employed in the Quran except literally, like the descending of the rain or revelation, we realize that this verse implies a very significant scientific miracle. Because, modern astronomical findings have disclosed that the iron found in our world has come from giant stars in outer space.[1]   Not only the iron on earth, but also the iron in the entire Solar System, comes from outer space, since the temperature in the Sun is inadequate for the formation of iron. The sun has a surface temperature of 6,000 degrees Celsius, and a core temperature of approximately 20 million degrees. Iron can only be produced in much larger stars than the Sun, where the temperature reaches a few hundred million degrees. When the amount of iron exceeds a certain level in a star, the star can no longer accommodate it, and it eventually explodes in what is called a "nova" or a "supernova." These explosions make it possible for iron to be given off into space.[2]   One scientific source provides the following information on this subject:   "There is also evidence for older supernova events: Enhanced levels of iron-60 in deep-sea sediments have been interpreted as indications that a supernova explosion occurred within 90 light-years of the sun about 5 million years ago. Iron-60 is a radioactive isotope of iron, formed in supernova explosions, which decays with a half life of 1.5 million years. An enhanced presence of this isotope in a geologic layer indicates the recent nucleosynthesis of elements nearby in space and their subsequent transport to the earth (perhaps as part of dust grains)."[3]   All this shows that iron did not form on the Earth, but was carried from Supernovas, and was "sent down," as stated in the verse. It is clear that this fact could not have been known in the 7th century, when the Quran was revealed. Nevertheless, this fact is related in the Quran, the Word of God, Who encompasses all things in His infinite knowledge.   The fact that the verse specifically mentions iron is quite astounding, considering that these discoveries were made at the end of the 20th century. In his book Nature's Destiny, the well-known microbiologist Michael Denton emphasizes the importance of iron:   "Of all the metals there is none more essential to life than iron. It is the accumulation of iron in the center of a star which triggers a supernova explosion and the subsequent scattering of the vital atoms of life throughout the cosmos. It was the drawing by gravity of iron atoms to the center of the primeval earth that generated the heat which caused the initial chemical differentiation of the earth, the outgassing of the early atmosphere, and ultimately the formation of the hydrosphere. It is molten iron in the center of the earth which, acting like a gigantic dynamo, generates the earth's magnetic field, which in turn creates the Van Allen radiation belts that shield the earth's surface from destructive high-energy-penetrating cosmic radiation and preserve the crucial ozone layer from cosmic ray destruction...   "Without the iron atom, there would be no carbon-based life in the cosmos; no supernovae, no heating of the primitive earth, no atmosphere or hydrosphere. There would be no protective magnetic field, no Van Allen radiation belts, no ozone layer, no metal to make hemoglobin [in human blood], no metal to tame the reactivity of oxygen, and no oxidative metabolism.   "The intriguing and intimate relationship between life and iron, between the red color of blood and the dying of some distant star, not only indicates the relevance of metals to biology but also the biocentricity of the cosmos..."[4]   This account clearly indicates the importance of the iron atom. The fact that particular attention is drawn to iron in the Quran also emphasizes the importance of the element.   Moreover, iron oxide particles were used in a cancer treatment in recent months and positive developments were observed. A team led by Dr. Andreas Jordan, at the world famous Charité Hospital in Germany, succeeded in destroying cancer cells with this new technique developed for the treatment of cancer--magnetic fluid hyperthermia (high temperature magnetic liquid). As a result of this technique, first performed on the 26-year-old Nikolaus H., no new cancer cells were observed in the patient in the following three months.   This method of treatment can be summarized as follows:   1. A liquid containing iron oxide particles is injected into the tumour by means of a special syringe. These particles spread throughout the tumour cells. This liquid consists of thousands of millions of particles, 1,000 times smaller than the red blood corpuscles, of iron oxide in 1 cm3 that can easily flow through all blood vessels. [5]   2. The patient is then placed in a machine with a powerful magnetic field.   3. This magnetic field, applied externally, begins to set the iron particles in the tumour in motion. During this time the temperature in the tumour containing the iron oxide particles rises by up to 45 degrees.   4. In a few minutes the cancer cells, unable to protect themselves from the heat, are either weakened or destroyed. The tumour may then be completely eradicated with subsequent chemotherapy.[6]   In this treatment it is only the cancer cells that are affected by the magnetic field, since only they contain the iron oxide particles. The spread of this technique is a major development in the treatment of this potentially lethal disease. Iron has also been found to be a cure for people suffering from anemia. In the treatment of such a widespread diseases, the use of the expression "iron in which there lies great force and which has many uses for mankind" (Quran, 57:25) in the Quran is particularly noteworthy. Indeed, in that verse, the Quran may be indicating the benefits of iron even for human health. (God knows best.)     Footnotes: [1] Dr. Mazhar U.

jurb6006@gmail.com: Sep 26 11:58AM -0700 >"The VW cars in queston are DIESEL, not gas. "   I have to admit that at first I didn't catch that. But then I did. However, doesn't the same apply ? The theory of EGR is to starve it for O2 a bit so the burning slows down. That should apply here as well.   But then I am not completely versed in all the pumps etc. these things may use. There was a time when they could not use a catalytic convertor on a diesel. Apparently things have changed. but what was presented really did seem to indicate that turning off the EGR except during a test was the issue. That is the impression I got in the beginning.   However, now other things are coming out, for one the allowing more fuel. But aren't those diesels just like the biguns ? There is no throttle, the injection pump determines the power output. Am I wrong here ? Where the hell would I get such information ? I can't just walk into a car lot and start taking apart their cars to find out.   As far as I know, diesels takes in all the air they can get so there is no controlling the mixture. It needs all that air to ignite the fuel. Putting in more fuel should not cool the burn, just make it burn more. Without a throttle plate the mixture is what it is and there is nothing that can be done.   Therefore the only way to control N2O is by EGR, and the article did state that the N2O may have been 40 times the limit.   Another poster somewhere in thread mentioned they should think about all this gas mileage and consider the pollution produced in the refining (cracking) process. Governments can be pennywise and poundfoolish really when it comes to things that require gray matter. Like what they did to flourescent lights. When I was in business I used them because they were more efficient and lasted longer. It was not a big business so I generally had the 4 foot 40 watt jobs. They lasted many years.   Then they came out with those frikken energy saving jobs and they not only flickered worse when cold, they also did not last as long. they totally disregarded the pollution caused not only by manufacturing more bulbs, but all the shit in the landfills.   One of these days I am going to contact the bleeding heart liberals about this. Lead free solder is used because of planned obsolescence, or actual planned failure to the point of unrepairability. This must stop.   Catalytic convertors are still mandated even though they are almost useless. At least in gas cars, with the computer they can run so clean they do not need it. In fact they could be tuned for better mileage and performance without it because there HAS to be some pollution and oxygen in the exhaust to keep the cat lit. The mixture cannot be stoichometric, which would be the ideal and pretty much the exhaust, except for mostly nitrogen, CO2 and H2O. But there would be nothing to catalyse.   Yup, they actually pollute on purpose to test the convertor. How does that grabya ? They are putting gout more heat, and less power and efficiency by mandate.   Beam me up Scotty, there is no intelligent life here. At least it seems. The fact is that these politicians are such motherfuckers that they may well know EXACTLY what they're doing.   Maybe. Generally, I have found intelligent people to be more trustworthy than idiots. They know the consequences of their actions. They become socially and morally responsible. So that means an intelligent politician might just be an oxymoron.

jurb6006@gmail.com: Sep 26 11:30AM -0700 What there is of a service manual is at :   http://exodus.poly.edu/~kurt/manuals/manuals/HP%20Agilent/HP%203561A%20Service.pdf   I do believe an actual schematic would help. I need the vertical deflection circuit.   OK, I blew out the power supply by making a short with the probe at the input to the -12 volt regulator. Of course it has an obscure HP part number on it but I can see it is a simple 7912 regulator. It is possible I blew it shorting the input if it has alot of capacitance on the output but that is not really an issue right now. First I will get the power supply up again. The referenced URL there has some basic block diagrams, and I am pretty sure I just blew a fusible somewhere.   But the reason I was in there in the first place is because it has a fault in the vertical sweep - foldover. Like on a TV when the boost cap or circuit fails, EXCEPT on this baby it is at the bottom of the raster as it does not scan top to bottom, but bottom to top.   It is not easy to follow this circuit because of the two sided board, but not impossible. The problem is that those people could put anything anywhere, and do. I can tell the vertical output is common emitter complementary push pull. The collectors are hooked together and are the output high side.   I do not see a third "retrace" transistor anywhere, but knowing how engineers are it might be on the frikken control panel or something. Also, retrace boosters are hard to implement with a common emitter push pull circuit.   I actually cannot see the yoke, but observing the high side of the vertical output I know it has one because it looks pretty much like the yoke drive in a TV. If electrostatic it would just be a sawtooth wave.   I would really like to see a detailed schematic of the vertical circuit here. I do not just "try" parts to see if that was the fault usually and I am certainly not going to start on something like this. I know that in instrumentation I cannot get away with some of the shit you can flub in a TV set or a stereo. I learned the hard way that when they say 15 volts they do not mean 16.5 is OK, it usually is not.   The thing puts out the waveform incoming along with the spectral analysis at the top. A sine wave was showing what looks like severe crossover distortion in an audio amp, but another scope confirmed it was not like that. Looked a little closer and the raster is not filling the screen and there is a compression right there. I also think I am missing one of the function names. They are on screen next to the buttons and none of that lines up of course.   Anyway, I am seeing hints of a "Volume 2" of the service manual which I suspect contains the information I want. I have been almost everywhere and it is not to be found. If anyone has it I need it, even if you have it on paper and could scan me a JPG of the vertical circuit would be fine. (if you can't get my email from this post I will give it to you, unless you can Dropbox it or something)   Really, I can probably do it without but it would take a hell of alot more time.   Thanks in advance for anything helpful.

jurb6006@gmail.com: Sep 27 08:58AM -0700 Thanks, that might come in handy.   Looks like I have to RTFM even with what I got. This thing shut down with a slip of the probe and now appears to need to be reset. There doesn't seem to be any bad components but there is no drive to the power supply choppers. I am going to make surer of that later today I think. It is difficult to access anything to test so I'll do hat I usually do - stick a wire on it and slide the card back in.   The way this thing is put together I can't even find the main transformer ! I pretty much know where it is but can't see hide nor hair of it.   This is another one where I look at how it is built and go "Why ?". They got the choppers on a standup car, the transformer on the motherboard and the rectifiers on another standup card. The logical assumption is they intended for service to be able to be performed on a modular level. All fine and good, but a part of me goes "Are you kidding ?".   I can't bitch. I couldn't design the thing at all. But I can go "Huh ?".   Anyway, thanks. And if you catch wind of any "reset" routine for HP stuff let me know. I am going to triple check that there are no blown components, like fuzibes n shit.
