Title: HP 6960A PSU anyone mains connector?
Post by: Kjelt on March 23, 2019, 05:34:14 pm

Another salvage from destruction by the iron melters and scrapyard handlers.
Am I crazy by saving this or are there more people like me who can't find it in their heart to let something like this just be destroyed ?

A HP6960A PSU, so cute, luckily without tubes or I would be lost (no tube experience here).
No this puppy has real Bendix B1203 TO3 solid state transistors. Anyone ever heard of Bendix ?  :-//

My question is does someone has a schematic for this small PSU ?
It does not look that difficult so probably will get it back in working condition but it still would be nice to have some paperwork and dates on it.

thanks.

Thanks that solves the first questions, the thing is almost my age  :)
Now I need one more thing, a fitting mains connector, fitting it with a new IEC connector would be a shame.
Also recapping I want to reuse the old cans, they look way to nice to discard.
