I have an AC/DC Magnavox TV, model RK3955 AL02, manufactured Nov.
1989.  It has a remote and pushbutton up/down volume with on screen
display.
Even with the volume all the way to minimum, it's still quite loud.

Hello all, I'm in the process of trying to decide what type of scope to
buy for audio work. What is the correct term to descibe analog scopes
that display the numeric readings right on the screen? Say for example
it will show you have a 3vPP signal and the freq is 12Khz? I know ...

If you can use one of these feel free to contact me. I obtained one in a lot
of stuff that I got at a local auction and I have no use for such an item. I
am looking to trade and or sell it. Always looking for most any car audio
related stuff (faceplates, stereos missing faceplates, ...

Anyone know of any sources of data (e.g. datasheets, connector pinouts, etc)
for a Samsung LT121S1-106 TFT LCD 800 x 600 display?  This was a fairly
common LCD panel in laptops (e.g. Compaq and TI) in the 1990's.  Failing
info on the panel, anyone know of any sources of technical ...

Hello at all,
I need to supply 9bulbs(12v, 35w cc each). I would like to find a suitable
power supply or other system to do it. Each bulb consumes 3A so, I need 18A
at 12v cc.

I have an HP8714C network analyzer with a GPIB connection to a PC.
Infuriately, Agilent Quicklink doesn't work with this model.  Does anyone
have shareware that will at least let me get screen captures?
Thanks,

There is a Celmacs SMT-8700 Pick and Place machine on eBay right now.
I can't find much info on this particular model, and think it might
be too old to do what I need.  But, it got me thinking about
getting a used machine.  I do very low volume manufacturing,

I've got a broken unit on the way.  Are the manuals for these
keyed to the serial number in any way?  Who's the best source
these days?
Please reply to NG.

One cell leaked some juice inside my Mini MagLight, and I cleaned the
threads and spring off and scraped all the residue I could off the
endcap.  But it still makes poor contact, even after I cleaned it again.
I googled for "remove corrosion caused by alkaline battery" and it came ...

  I am looking for TSK-UF200 GPIB protocol.
I was trying to find it on Google but no luck.
I need to know what should be send to prober to inform about bin number of
tester device.

I got a nice discard 2245A scope that had been rack-mounted, so it was
missing the handle.  Anybody know where I can get one or what other
models would provide suitable substitutes?  I've checked eBay and my
local junkpiles and have been coming up empty.

A few years ago I purchased a used Kikusui COS5020-ST oscilloscope and
now I would like to calibrate it.  Google turned up an online manual
message board (http://servis-manual.com/) and on June 21 someone
posted "Kikusui COS5020-ST.doc"  If anyone has this or knows where I
