No but it's limited to 5A, not sure if I would see it jump. Transformer/windings look in good shape. Rails not changing by moving it around.
One side ~1.96V on all, the other side 3.2V. Hmmm
~6.7V on all
The gate voltages should be the same. Did you change both PNP drivers?
Is the DC voltage on both outputs of the 3524 the same?

No just the one side that is measuring 1.96. I changed the 2n2222 on that side too. I have extra parts of both.
Pins 11, and 14 are both measuring 1.96V.
Replaced the other PNP, now current draw was ok, 12V was steady but then the 22ohm 2W wired across the transformer feeding into the rectifier diodes started cooking and it was no longer pulling excessive current. I can't win with this LOL. I had to current limit to about an amp to keep it from being toast.
It was smoking, I could visibly see the magic smoke starting to come out...I had to shut it down before it cooked completely. Any ideas where to look now? Diodes check on the rectifiers still seemed fine.
Could it have simply been oil burning off of it?
Do you read the same gate voltage for all of the power supply FETs?

Ah, now that I think about it it was probably the deox I had sprayed on the switch to clean the contacts. I probably got some on the resistor when I was spraying it.
I re-installed the filtering inductors and all is good. No problems that I see now. It needs a full test now with loads but power supply is good to go. No more excessive current. Thanks for you help, I learned a few things too in the process.
Do you have an A/D/S PS5 manual in your collection? If no, would you like scans of it?
