Thanks, that's the info I was looking for! So I will monitor the idle current and adjust the cathode resistor value if needed.

Have you tried using a pot (rheostat) on the plate to adjust the voltage? I know the guitar guys like to do that sometimes. If so, what pot did you use (wattage, ohms, etc.).
