[time-nuts] Fail on HP5065A PSU repair

[J. L. Trantham]

Magnus,

If you are referring to the A15 board, I may have a spare.

I have been collecting parts for a couple of years and I *think* have
everything except the A12A1 Spectral Lamp Oscillator Assembly.  I have found
some dead parts on some boards that I have replaced and, as best I can tell
from measurements on the A12 RVFR Assembly, everything is OK but I can't go
forward until I get the Rb lamp assembly itself.

If I can find that, I can bring this to a conclusion (happy, I hope).  Once
done, there will be some 'leftovers', one of which will be an A15 board.

Joe

Fellow time-nuts,

I'm sure you all have done this at least once. Repaired something up, 
feeling happy about it, slap it in and then if fails on you again.

The transformer in the DC-DC converter failed again. Popped the lid even.

*sigh* I think I will have to rebuild that from scratch.

Cheers,
Magnus
