That means we still have a problem in the chassis. I THINK it has to do with the DC protect board. It is supplied B+ voltage off the backplanes, and there are a couple diodes that look toasty. I'll hook things back up and isolate the DC protect and go from there....
I suspect so as testing all components is costly.

Make sure you check for no shorts of each winding to the transformer case/laminations.

Transformer windings are good....
Not theirs Lee but have toured numerous others...
Good to hear, it is all repairable then.

Yes, still leaning towards the DC protect board as my problem. I've probed around the backplanes A LOT and can't find a short there anymore...

It is not the DC protect. Isolated the DC protect and still have a high current draw on the B+ rail...
That's good to hear. I was wondering if that was true based on the price.
The price is based on the die size of the silicon and the package cost primarily.

That cured my high current draw, now the bulb does go dim...
