Reflowed the solder joints, didn't change out the diode, I get a somewhat better result now.Anode of the diode, HV AC voltage from the auto transformer.[ATTACH=full]123295[/ATTACH]HV DC supply at one of the tube HT pins. It takes awhile for the cap to charge up to 40V plus, before starting to decrease in a steady pace.And why is there a need for two HV caps in parallel with different capacitance? a 33uF (brown sleeve) and a 10uF (blue sleeve).Why not just put one 47uF instead?[ATTACH=full]123296[/ATTACH]I guess I do need the amplifier's main transformer and the tube to do a further testing. Will update this thread when I have them on my bench this weekend.
