Re: Replacement caps for Tektronix 434 Power supply board.
You put in new C924/C925?
R926 I think could only smoke if diode CR924/CR925 are shorted. If the cap C924/C925 arced/shorted, could have taken out the diode(s).
Tektronix 152-0242-00 is 1N486A Si low-leakage switching diode 0.2A 225PIV; superceded by 1N486B
Or there is a short on the PCB. Maybe also multimeter test Q924 and Q925.
I cut out the page we are talking about: TEK434 s/n below B500000 schematic page 173
