- The filament transformer I am using with an 811A amp has no CT for the B- return, so I just tapped one side of the filament. Is this a good idea or am I asking for a hum problem here. If I make a CT

- You'd be asking for hum. Rather than using a couple resistors, you could simply take another small 6.3 v transformer with a CT on the secondary and connect it across your filament transformer and jus

- - 2, 3 - 5 ? resistors in series would provide a C.T. with less DC g-k bias change due to cathode I x R/2 drop. cheers, Ed - R. L. Measures, a.k.a. Rich..., 805.386.3734,AG6K, www.vcnet.com/measures
