Let us assume one is the form of the variable plate voltage regulator, which would cause us to ask the question, what is the tone for a low voltage operated pentode ? Well, you may hear different opinions on that one.
Then, let us assume the other is the circuit that I use, which leaves the plate voltage at a constantly high level, and only varies the plate current that flows through the tube. I prefer this method because I believe pentodes only sound good with high plate volts. I've ready heard hear a few "choice" opinions on that one. But the guys who play though my amps here in the bay area seem to like getting those cranked sounding tones between, I'm guessing between 3 to 4 watts when playing on stage.
