I have an OLD homebrew supply for a single 4-1000, that needs some re-work before using it with an amp.Transformer weighs 103lbs, with a 28 lb choke input in the neg lead. Rectifiers are 3 amp individual diodes in a bridge configuration. Questions are: is 16Mfd enough at 5 Kv and 540mils, if not, how much? And why will a variac cause poor regulation? 73, Mike W5CHR Memphis _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
