AF6LJ:
Just acquired this from a friend in non working condition.
The +5V supply was repaired and in the process I managed to break the +40V supply.
Fixed. and all appears to be working.
Just a basic HP-8901A modulation analyzer.








No you don't get top see the repair. No smoke got let out, however I don't consider a transistor bodged to the back of a PCB to be up to my standard of quality.
But Hey!
The SOB works!

capt bullshot:
Saved this stuff from beeing scrapped:

An ENI 13.56MHz / 300W RF generator, was probably used for some kind of plasma stuff,
Prema 2080 Scanners,
Some guts of another ENI 25kHz to 125kHz / 800W plasma generation power supply that someone else decided to take apart before. The controller board, containing some interesting ICs like the MPY634, the impedance matching output transformer and the driver amplifier stage.

The scanners appear to work, I haven't tested the RF generator yet, I don't have a suitable dummy load / attenuator. If it works, maybe one can build a plasma speaker driver from it? I've got little use for a 13.56 MHz CW source alone.

VK5RC:
A free 7603 non working mainframe.
A few hours of time found 3 dead electros (short)  had taken out two rectifiers and a PCB trace (hiding above the transformer). I had to buy the parts and the plug-ins. Those big electros aren't cheap.
She lives!

Hell that looks tidy, congrats on your score.  :-+

AF6LJ:
Lots of good stuff, our members have scored lately.
:)

I have acquired more, we will roll it out as time permits, and gaps in current project's progress will allow.
