RCA CTC 130A (Note this chassis has no PW VIPUR Supply) Blows H.O.T repeatedly Changed the H.O.T transistor and checked flyback OK. Checked caps in the H.V section OK. Soldered the driver transistor and transformer. The driver pulse is there but is pulsing. I can't remember how to trouble shoot this supply so it does not pulse trying to start. I want to variac the B+ at start up to monitor the driver pulse. thanks for any info, Bruce.
