Hi all,
Has anyone seen a schematic for the 6550/6H30p/Fet power supply used in the REF10/REF3/PH9, or a DIY version? I have and older PH3 (that I'm converting to a PH5) I would like to add this PS...to keep the ARC flavor.
I take it the 6550 is the pass tube, the 6H30p the control tube ...but the Fet ... part of the control circuit?
Anyone know where could I find a R core transformer?
