Philco Safari

[JSMCMS]

Hi All, I am restoring a Safari H2010L and it is going pretty well however, I'm only getting 4KV of high voltage to the picture tube. I've recapped the set and it works fairly well but I get substantial blooming when I adjust brightness. I suspect weak 5642 rectifiers but before I jump into that mess, can you offer any suggestions on how to best troubleshoot this problem?

Been a while since I looked at the schematic, but if it has a flyback derrived B+ boost rail check the voltage on that...If it is spot on then your HV rectifiers are suspect.

ESRC has 5642's for a buck each.
