That's not where you need the bias resistor, you need it after V1.

Wouldn't that be at V2 after the coupling cap? V1 has a grid choke.
Dennis suggested 350K or 250K.
Yeah, oops, after V1.
With a 0.1 uF coupling cap, Dennis' suggestion, start with about 350K Ohms, listen and measure, then TRY 250K Ohms, listen to that, makes very good sense to me. I am glad Willie is open minded enough to give it a TRY !!There may be a run on 5VCT at 3 A. wall warts, at local thrift stores, all over America now !!!
