Columbia 817-6

[Doug66]

Here's what I found out. With pin 8 f the flyblack disconnected, it puts full B+ across that Cap C3 which caused it to explode. Connecting pin 8 back up pulls the B+ down to 250V BUT only puts about 3V across that cap. The original cap was a 12V unit.

R100 has been replaced

When I started on this set, I 1st replaced C1A and C1B. I have since re replaced them but that hasn't helped.

Could it be in the flyback even though I have good HV?
