Bruce | Re: Ampeg R-12-R clone... nitpicking q's Yes, it is there as a filament hum reduction circuit. Keep it there. That is DC voltage not AC voltage and as long as the filaments are not grounded anywhere, it is correct. I run the center tap of my filament supply at close 30vdc from a seperate + supply on fixed biased amps. Measure AC from pin 2 to 7 and you should see just the 6.3vac. Bruce |
