Hey guys. Yes I picked this one up and recapped it already. Threw in a good 19AP4 but have no HV anywhere. Cannot seem to track down the issue yet. I need to rig the set so I can run it outside the cabinet so I can adequately test voltages. That's the next step. I do not have any HV at the plate caps of the dual 6BQ6s. Cannot hear the horiz oscillator running at all. That indicates to me the issue is before all that, correct? Chassis is 24H21, model number H2447R. Flyback "looks" ok, but have not even gotten to that point yet b/c I think the issue is before that with no osc. running and nothing at plate caps of 6BQ6s. Any ideas would be appreciated. I have good sound and she is solid. Have run it for around 20-30 minutes while fiddling with no apparent other issues popping up. Few photos attached after getting it home and cleaning it up a bit. Oh, I have checked the continuity of the phonevision shorting plug as well. All ok there.

Schematic is here. Pages 23-24 of the PDF file.
