[GreenKeys] Kleinschmidt Power Supply PP-978/FG: Replace Selenium Rectifier

[Steve Garrison]

Just open the windows and turn on a fan if the smoke gets out.   I only had one or two give up the smoke during my time in the AF, and it doesn’t seem to have affected me.  But now I don’t run my Kleinschmidt machines with selenium rectifiers 24/7, but so far none have let the smoke out.  In fact one of the later model ones with the potted full bridge rectifiers gave up the smoke.   But when I contacted the manufacturer, whose name and company logo was plainly printed on the device, they claimed they never made such a device and would be of no help finding a replacement.

Greenkeys,

 

I am getting a TT-98B/FG up and running and would like to replace the selenium rectifier in the power supply (PP-978/FG) with silicon. If anyone has experience doing this with this particular equipment, I would very much appreciate the help.

 

Best,

 

Joe
