[QUOTE="Ampdog, post: 9813, member: 144"] I would advise reading the "Quiet filament supplies" by Lynn Ohlson under Amplification. Too often folks think that simply slapping a bridge and huge electrolytic between transformer and heaters gives a dc heater supply ...."Ah, I have dc on my heaters ..(smirk)" Not to repeat, but that sort of thing often yields such peak transients on charging the reservoir capacitor that it is no better than simple docile ac on the heaters. In fact, I think I will open a new topic on this elsewhere; might just help a few members. Thanks F D. [/QUOTE]
