I am afraid that is all Greek to me Eli. Anyplace that has diagrams of how all that is done? I understand the first half of your reply but you lose me after that.
Actually for now it will be temporary even with two channels. What size resistors are you thinking I should use?Also, I could just hook up the second 2A3 filament and have it balanced that way yes?

Vinnie,
Generally most DHT tube amps or preamps use separate filament trannies. Then you can use a hum balance pot to null out any hum(to a certain amount). But because you are going to use both windings of the tranny with a common center tap(0) the balance pot is out and then you will have to incorporate an RC(resistor/capacitor) filter.
Or switch it to DC maybe? Thanks for the explanation. How would I calculate what I need for the R/C filter?
Thanks
