legg <legg@nospam.magma.ca>: Mar 27 12:00PM -0500 This issue with 'cheap' vs neutrik:   You should all be aware, by now, that these connectors are all made in China - that difference in price is solely a distribution and sales issue - that quality is either demonstrated or not by the product itself - associated by trade brand name.   Therefor; there's no point in complaining about the quality of a part without identifying its brand name or mfr. Without this info, the warning is meaningless, because price is no longer a valid identifier.   As an example, recent Neutrik connector types, not commonly stocked domestically, were ordered at >$25 a pop and delivered from Shuersi Inc in Nanjing. Not cheap, good quality, reputable brand name from China.   Expecting these things to be manufactured by gnomes in Luxembourg is pure fantasy.   RL     On Wed, 16 Mar 2016 18:34:37 -0000, "Gareth Magennis"

jurb6006@gmail.com: Mar 26 11:26AM -0700 >"f you have an questions, please consult a real attorney. "   HA. Half of them are incompetent and the other half, well...   Used to work for one of those rental joints. Handled the repairs for the area, approximately the county. They reanted BFC SFS Fisher stereo systems using the CA-270 (discrete) amplifier. I worked on many of them. Underbuilt, and on purpose.   Looking at the PC board it was easy to see that it was designed to have commutators. The thing was considerably over 100 WPC and only had one pair of outputs per channel. You can get away with that with a commutating power supply. Also by the relay you could see the traces for what was obviously an offset detector.   All these parts were gone. By the relay all that was left was the time delay and the commutators were simply jumped out and all related components were omitted.   We replaced so many woofers because of that it ain't funny. Eventually the service manager got a source for some practically bulletproof woofers, I mean woofers that would stand up to 60 volts DC until the fuse blows. At least that was solved. Kinda.   Thing is, transistors and diodes are cheap. If I were on that side of that desk I would have them in there. However, in the US at least, the quarterly report is king.   Like this joke... A new CEO of a company gets three envelopes from the old CEO, tells him open them when things get tough. Sales drop later and he opens the first envelope and there is a note saying "Blame your predecessor". He does and all is fine, but later then sales and profits drop again, he opens the seconfd envelope and the note says "Reorganize". Well that works but then things go badly again later so he opens the third envelope and the note inside says "Get three envelopes and..."   As long as we publicly trade debt on these companies, they are bound to suck up the most money every day possible, It is fucking up the world, and the environment. In fact, if we cared enough to do something about it we would take the "green" attitude and let the democrats have at it. Laws that say you have to have parts for TVs n shit for like five years or so, instead of having them no longer available even during the warranty period. (this has happened) But even with that, can the government control the prices ? This is where they fucked up on the ACA, the price controls are not firm. Right now health insurance companies want doctors and hospitals to fuck them out of as much money as possible so they can make 20 % on it. Shit, oil companies would suck a mile of donkey dick to make 20 %.   The informed and non-addicted consumer is the best weapon here. Like "My TV was only two years old and it couldn't be fixed, I went to buy one with a long warranty but they had none, so now I DO NOT HAVE A TV". Start that shit and you won't need a grass roots lobby organization, the TV networks, cable companies and even Hollywood would do the lobbying for you.   But there is no solidarity among the sheeple. No chance to put up a serious boycott of anything. Anything. This is the age of instant gratification. Pitiful fucking species they are.

Half of them are incompetent and the other half, well...   Shakespeare had it dead-right in his play Henry VI. Killing the lawyers was the sure route to tyranny, not the means to restore sanity to society.   Keep in mind that it is "society" that gives or has given us every evil from the Crusades to Jihad and ISIS, from Empress Wu to Donald Trump. Society is essentially insane, and functions only through pitiless and unrelenting control. Where such control has been destroyed, all remnants of societal function have failed. Modern examples include former strong-man states (Libya, Afghanistan, Iraq) where leadership was removed, not deposed. States where leadership was deposed (Iran, Soviet Russia, Balkans amongst others) function today after a fashion, and after an often horrendous shaking out - but they function none-the-less.   Circling back to electronics - we get exactly what we deserve, neither more nor less. It is entirely possible to purchase well-made electronics that are maintainable and have a truly indefinite service life - with that maintenance. Including all consumer entertainment electronics in this household, the newest daily-driver type item is a 6-year old blue-ray player to match the 8 year old plasma TV. The oldest is a 1962 tube stereo amplifier. If hobby (and functional) electronics are included, that would be a 1919 5-tube home-brew TRF radio driving a Magnavox horn.   If that first pair of $3.29 pair of Chinese underwear stayed on the shelf for the $3.69 pair of home-country underwear, we would not have this issue. But we are all-to-fast ready to give up our neighbor's jobs to 'save' that $0.40. Not quite understanding that without our neighbor's jobs our own are not long for this world.   Sorry for the insertion of politics here - but feeling sorry for ourselves is the last collective and several refuges for cowards. And "Let George Do It" is how we got here in the first place. The Chinese have not "taken" one single job from any one any where at any time. They were handed each and every one of those jobs complete and together with the plea "PLEASE take this burden from us!"   And. Lest ye "first world" people think for one hummingbird heartbeat that control over *you* is not pitiless - consider how much *you* are regulated, and at every turn. Between taxes, leases, licenses of various sorts, permits, insurance, credit cards, cash-transaction limits, speed limits, stop lights, parking meters, passports, health insurance, deeds, titles and on and on and on...   Put another way, Anarchy Bitch.   Peter Wieck Melrose Park, PA

jurb6006@gmail.com: Mar 26 02:17PM -0700 pf, politics is what started this shit.   I used a slightly different analogy.   When you walked into Kmart and saw TVs on the shelf, a Zenith for $279 and a Sanyo for $229 you pocketed that fifty bucks and went and had a good time on it. Well the good times are over because YOU told the industry that cost is King, that you want it cheaper. You did not care about build quality, or this country and its well being. You wanted that half a yard in your wallet.   Time marched on and the results are in. We are fucked.   I see you think like me to some extent. Have ANY ideas on how to fix this shit without removing 90 % of the population ? I can't figure anything out. Even massive killing wouldn't work. NOTHING will work.   Reminds me of a joke about an old Indian. (American) Guy asks him about what he thinks about White Man. He replies "We had it good, Women did most of the work, we hunted and fished every day, no taxes, no debt, no problems. Only White Man stupid enough to think he can improve on that".   Progress. Think about progressives. Now think about conservatives who wanted to keep things the same, for better or worse. In fact republicans freed the slaves. Things seem to have flip flopped.   Slavery is a barbaric thing and should not be allowed in any civilised society. It is illegal in most parts of the world, but not in Israel and a few other countries in that region and in Asia and Africa. And that saying about "we should have picked our own cotton" has come true eventually for most countries that had slaves. Now it seems we should have picked our own oil.   But there are no true conservatives. I think the last one was Barry Goldwater, and he warned against letting the religious folk get hold of the republican party, because governance is all about compromise and people who think they are speaking for god will not compromise.   While he was right, he did not realize that later (like now) that these people would not be religious at all, but feign it for church support. And that is important in some districts. Like against homosexuals until their son comes out of the closet. Or against abortion but sends their mistress for a D & C when she gets knocked up by their adultery. Fucking hypocrites to the core.   Nixon was more of a Man and more honest than any of them today. Think about it, if you are doing backdoor deals and being dishonest, do you want tape recordings of it ? some say he did that because he was paranoid but the fact is they were out to get him. I believe he benefitted from the Watergate breakin, but I still do not believe he ordered it. However, like the impeached Bill Clinton and the assassinated JFK, he spoke against Israel. Most people do not know that alot of this shit happened right after they said mean shit to Israel.   So, with no true conservatives we are stuck with the liberals or oil company executives. That is your choice. Who are you going to vote against this time ?

Have ANY ideas on how to fix this shit without removing 90 % of the population ? I can't figure anything out. Even massive killing wouldn't work. NOTHING will work.   I am not so sure we think much alike. My politics as-practiced are considerably left of center, although not quite socialist. Mostly based on personal responsibility, the social contract and the basic fact that the world owes me nothing.   At the same time, the Human Race if seen as the functional equivalent of mold on an orange is doing a very efficient job of killing itself off, and apparently sooner rather than later. No problem for me, likely not for the kids either. But the grandkids are going to have a brutal time of it. A few tens of thousands of years from now, we will of interest only to whatever passes for archaeology and paleontology at the time, if even that. So, why sweat the small stuff with that perspective?   As of this moment, and based on present absolutely provable facts and long-term trends, the Malaysian archipelago land mass will be reduced by 70% (or more) by 2050. The present population is just under 30,000,000. And there is not one damned thing that you, I, or anyone else, collectively and severally, can do about that. AND, that is one single example. Florida - what happens when 30% of that state can no longer support either farming or a human population? New Jersey (small loss)? The entire Gulf Coast? Not to mention California. Just keeping it "American" here - the rest of you are also quite done, just not fully aware of how done, quite yet.   That we are fucked is absolute. That it is of our own making, equally so. But as a species we have always been better and destruction than at creation. Always. This particular disaster is pandemic, having nothing to do with race, color, creed, nation, state, orientation or personal preferences. Like a flat tax, we are all equally affected whether we like it or not.   Peter Wieck Melrose Park, PA

A mechanical engineer bought some, and saw those little plastic things clamped under the transistors and decided they couldn't conduct heat well, so he took them out, put a glob of thermal grease under them and clamped them down tight. Hooked the whole system up and turned it on. There was a thunderclap and a huge flash, and everything he had bought from me was reduced to charred rubble. The little plastic things were good Bergquist thermal conductive pads, and work fine to allow the amp to run at 20 A continuously. I fixed one amp just to see how bad it was, well every semi in the thing was toast. It must have got +80 V into the +12 logic supply.   That's the biggest idiot I've had so far...   Jon

Second time I had to repair it I checked what he was actually doing and found the reverse polarized battery. His car was an early '60 Ford van with a generator, NOT an alternator and when the battery was dead he jumped it backwards and converted it to positive ground.   G²

T i m <news@spaced.me.uk>: Mar 26 09:38PM Hi all,   I was asked to look at an electric scooter for a friend today. His friend bought it directly from China, ran it ok for a couple of months and then it just stopped working (so no point trying to send it back from the UK).   Whilst I'm reasonably comfortable with basic electrics and electronics I'm not familiar with the sort of things you find now days around Lixx type cells and packs and hence why I am looking for some advice here please.   FWIW, we connected the 36V, 40 cell pack (possibly 4 x 10 or 10 x 4 in parallel?) up to the scooter charger and saw the terminal voltage go from around 36 to 40V (charger max 42V) and the current initially sit at 2A and then start dropping to about 1.8A after maybe an hour. I believe the cells are these:   http://www.ax-ps.com/pdf/datenblatt/LR1865_SI.pdf   (making the pack ~36V x 8.8 Ah)   Putting a load (3 x 12V x 21W lamps in series) across the battery output showed nothing. Putting the load across the cell monitoring wires (eg, directly on the battery) had the lamps shining brightly (indicating there was nothing wrong with the battery itself, at least with a load of around 2A)?   We then turned to the BCM, un wrapped it and found and tested a (65 degree) thermal switch and that seemed ok (short cct).   I've since split the BCM and this is the working side (the other half is the monitoring board [1] and connects the main board via a 4 pin link shown at the top):   https://dl.dropboxusercontent.com/u/5772409/BCM%201.jpg   The two wires you just see top right go to the 5A thermal switch, the blue wire top left is the negative out ... and the pad J2, top right is as marked, connected directly to the battery -ve. So this board and all the cell monitoring connections work WRT the battery Ov?   The charging connector is basically across the output.   Now, from Googling about I think I understand some of the components on that board may control the charging and that seems to work (or at least not be dead), so I think we are looking at something that may enable the output, presumably as long as the battery voltage is sufficiently high and the pack temperature is less than 65 DegC etc?   The T0-220 devices seem to be 3 x RU75ND8R mosfets + 1 x HY1807.   https://dl.dropboxusercontent.com/u/5772409/RU75N08R%20datasheet.pdf   https://dl.dropboxusercontent.com/u/5772409/HY1807%20datasheet.pdf   From what I can see the gates of the two devices to the left are driven from the two EL817 photocouplers seen bottom left.   https://dl.dropboxusercontent.com/u/5772409/EL817%20datasheet.pdf   I found something that might give some hint of a similar issue here: https://endless-sphere.com/forums/viewtopic.php?f=14&t=67012   And a more detailed description of how it might work on the last post: https://endless-sphere.com/forums/viewtopic.php?f=14&t=67012#p1008437   So, I'm not sure where to go next. I do have one of those little component testers so, assuming I couldn't test the power devices in circuit I could de-solder them (FETs) and may be able to test them but what are the chances of that being the fault and it not be some of the other (SM) circuitry please?     Cheers, T i m   [1] https://dl.dropboxusercontent.com/u/5772409/BCM%202.jpg https://dl.dropboxusercontent.com/u/5772409/BCM%203.jpg

Or at least do the two that don't seem to be involved in the charging (that I believe works etc).   Cheers, T i m
