I just recapped a HV unit on a tempest. In the process I replaced Q901
(MSPA06) and R904 (470 1/2w).
The monitor turns on and has a reasonable display.
BUT: My B+ voltage is 56v (checked at Pin 5 of the J900). I can't find my
HV probe to check what the HV is at right now.
The pot on the HV board doesn't make any difference to the b+ voltage.
Before I start to just shotgun parts (R918 the adjustment pot, Q902, Q903)
anyone have any suggestions?
Thanks,
David
