If your still on the dimbulb probably explains the low voltages. ie +/- 33.5vdc
Yes, I have in on a dimbulb, 100watt. I figured that would be safest, but I can always try it without if that would help.

Possibly D164 is the culprit.
No sir, I did not.Did you replace the 4 large caps ?
See if there is any AC voltage there.
Oooh .. That don't look very good..I went ahead and checked for AC on all the output collectors. Here is the results:
LP+ 73.8
LP- 0
RP+ 107.9 <------The 49.2 Vdc one
RP- 0
Gonna have to pull that one to check it, aren't I..Possibly D164 is the culprit.
Might as well check D163 as well.But I'm leaning toward D168.Gonna have to pull that one to check it, aren't I..
You mean 164?But I'm leaning toward D168.
No..D168 the bridged rectifier.You mean 164?
No..D168 the bridged rectifier.
Yeah I'd definitely diode test everything in-circuit first (both directions) to see if you spot anything fishy or inconsistent.
I think you can get to everything (even the 4 diodes), use some scrap wire if you need to. It's a pain to pull the caps if you don't have to.
