Another way would be to cram a wad of paper between the door and the oven, and use a microwave leakage detector to measure the resultant leakage. It there's a slow rise in output, you'll see it on the meter, which you won't see on the CD.   -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

There will be a sequence as others have noted: Fan-Start, relay click, magnetron start.   b) Then, it depends. We have a 1,100 watt Panasonic that is very fast-cooking to the point that we are very careful of the setting as even 10 seconds makes a difference. A 500-watt device will provide an entirely different experience.   So, it is a combination of the onset time and the actual power of your microwave that will give you the answer. But what is obvious is that 2 @ 5 seconds is NOT 1 @ 10 seconds. The reality is that a 5-second setting will give ~1~2 seconds of actual full-output heat. 10 seconds will give ~6~9 seconds.   Peter Wieck Melrose Park, PA

boomer#6877250@none.com: Dec 01 04:02AM -0600 I have an inexpensive pair of powered computer speakers. I didn't pay much for them. but they have worked pretty well for the last year or so. All of a sudden they became touchy and would not turn on, or would shut themselves off.   Bending and twisting power cord makes it work (maybe), for a short time. The power comes from a wall transformer labeled output 7.5V 350MA. The plug on the cord end that plugs into one of the speakers looks like this: http://www.jameco.com/Jameco/content/walladapter-fig5.jpg (probably not the same dimentions)   I put a meter on the plug, wiggled the cord and there is no loose connection. I opened the speaker and found that if I wiggle the male plug socket soldered onto the circuit board, I make and break the connection. Using the ohm scale on my meter, it appears the outer shell terminal is the one at fault. (Not the center pin). Pushing a thin jewlers screwdriver under that plug seems to maintain a connection.   In brief, that male connector has a bad connection and needs to be replaced.   I am aware these plugs come in many sizes, and finding the right one could be a challenge. That eliminates shopping online. This leaves me with only Radio Shack, meaning I'll have to take the transformer along and see if anything fits.   My question is DO THEY MAKE INLINE MALE PLUGS FOR THESE KINDS OF PLUGS? Im sure finding one that will fit on the circuit board will be near impossible. But I could easily run 2 wires out the back and solder on a male inline plug.   If all else fails, I will probably just cut the female plug off the cord and solder the cord right into the speaker. I'm not willing to spend much money or a lot of time on this project, but they work fine othewise so I want to fix them.   By the way, is there a name for this type of plug?

I bought some male and female pairs a while back off ebay for only a few dollars. Maybe you can just buy a pair of them to get the sizes to match and replace both pieces.

ohger1s@gmail.com: Nov 30 08:58AM -0800 This is for a good customer who wants this toilet fixed for sentimental reasons (so he says). It has a shorted STK4152II that's putting the -Vcc on the speaker terminal on one side, the other side is working. There are no relays of any kind in this receiver and I can't believe there isn't some sort of speaker protection scheme incorporated, not even speaker fuses. Even Pioneer's suicide circuit was better than nothing at all.   Anyone have a schematic for this? Also, the STK4152 is a discontinued device, but there are plenty out of Hong Kong. Anyone use one of these generics recently and had good success with it?

Sometimes you need to invert the mute line control though

jurb6006@gmail.com: Nov 30 08:51PM -0800 Those knockoff ICs are almost never good. Real NOS is hard to find.   I couldn't find the print on the receiver but the chip is only 30 WPC which means you can use a couple of LM3886s in it, just figure out how to remount, use the inverting and non-inverting, hook up the power and the speakers, and you need a resistor to the muting line. Get them clamped to the heatsink and you should be alright. I did that on a Mitsubishi X-11 system. I almost wanted to just put preamp outs on it and tell the guy to use an external amp but they put the tone controls in the output feedback so they would not work unless I got some OP AMPs and this was just a better solution. Just hook up the speakers and you are good to go.   Cook wants to rebend pins but what I did was to turn the upside down and simply wire the pins to the board where needed. That way the pinout doesn't even have to come close. Ad the LM3886 is a six wires solution, and one of those is the muting and only requires like a ten K resistor which can easily do both channels. Don't even entertain the idea of leaving the working channel in there. Too much PITA and for no good reason.

I'm not going to invent the wheel on this thing; it's not worth time, sentimental reasons be damned. At the end of the day, I still have to bill by the hour. A cheaper solution which I've used in the past is to buy complete used receiver on ebay for parts.   My questions were if anyone had successfully used the currently available STKs and this indeed has no protection scheme (hence the request for the print).   In any case, I'm sure one of the Nesda members has an OEM STK somewhere and I'll post a request there if I'm not confident one of the currently available STKs are not suitable.   Thanks for the advice guys.

captainvideo462009@gmail.com: Dec 01 05:52AM -0800 > I have an old Dell Lattitude D630 laptop. Is there a way to come out of the VGA jack on the back of my laptop and somehow end up with composite or S video out? I tried an adapter that my son said he had used to do this in the past. It plugs into the RGB jack in the back and it has two short cables out of it. One has an RCA female jack on the end of it and the other has an S video female. I didn't try S but although I can get an image on my composite monitor you can see that there is more than one image and it's out of sync. I tried adjusting the display settings and that seems to put the frequency way off. I used to have a video board on an old DOS computer that had an RCA jack on it and it was very handy. Is this still possible to do? I think that I read somewhere that anything ten ears older or less should be able to support this. I don't know how old my laptop is but i don't think that it's over ten years. Thanks, Lenny   I thought "perpetual motion" was a theoretical quantity, kind of like the square root of -1. Lenny

I did a quick Google search and found many references to it so clearly the problem is my memory (or lack thereof).

Jeff Layman <JMLayman@invalid.invalid>: Dec 01 09:19AM > place.   > Color me dubious.   > Peter Wieck Melrose Park, PA   How would they do this in practice? If it had to be done in a hard vacuum, how would you transfer the heat away from the valve to cool it down to -184? Maybe they hire a rocket to fire the valve into space and let it cool down by radiation, obviously keeping it out of sunlight while it's up there. ;-)   And why would they do it to a rectifier tube?

"Stephen H. Fischer" <a_nani_mouse@mindspring.com>: Nov 30 01:49PM -0800 One problem with multiple lens in each eyes is sun glint during the sunny days and LED lights in dark rooms. After five years my mind is only partially reducing that effect. Any bright spot on DTV with a black background will have a halo.   I do NOT drive at night and do not recommend any one with multiple lens in each eye to do so.   The 4th of July Fireworks is interesting, each spot of light is a little Saturn with rings.

My daughter doesn't even notice that with hers.   Don't you lose your binocular (3D) vision with that setup? I was offered that for my implants but declined. I never really minded wearing glasses all that much anyway. I have my implants set for indoor distances so only really need glasses for reading and driving.   > Cataracts turn the lens yellow.

Between eyes I went to a Savers store and found some used glasses that had a lenses that worked for the new eye and knocked out the other lens for the old eye. Worked surprisingly well for that time I had unbalanced eyes. Looked a little weird though.   I've had the implants in ten years now with no problems. My eyeglass prescription never changes anymore which is nice. For some reason my pupils now give a green reflection which gives my grandkids a charge.   For those contemplating the procedure my only advice is don't wait.

The out-of-focusness isn't that bad, especially when my pupils are stopped down. I would never have selected monovision IOLs, but I was surprised at how good the contacts are.   I had my IOLs set for distance. I spend most of my time doing close stuff, but I want to be able to see without glasses outside, which seems much more urgent. Besides, the 99-Cents-Only Store reading glasses work just fine, but you have to pay to get prescription distance glasses!   When my mom had her cataracts done her ophthoquack decided she should have near vision, which meant that she wore trifocals and hated them. She was really angry when I found out and told her that she could have chosen distance if that's what she wanted. The quack was a quack in other ways too, and another ophthalmologist spent half an hour on the phone trying to convince me not to report the bastard to the medical board. He won -- I knew I wouldn't be able to get a doctor to testify against the quack, but I was seriously thinking of picketing his office. Mom didn't want me to, so I didn't.

Glasses still improve my vision, but it's just SOOO much better than it was that I'm not about to complain. Well, maybe a little...   > I've had the implants in ten years now with no problems.
