I started with a 10k pot in series and it wasn't enough so I bumped it up to a 25k pot and it got close but not enough so I changed out the power tubes with a matched pair of NOS RCA tubes and it got to a perfect spot. Plate voltage at 510 DCV with the bias set to 40.5 mA. I can live with that for now until the BMK kit arrives.
