The schematic you supplied with a previous post showed an amplifier
with only four tubes. The amplifier you show with your second post
shows an amplifier with five tubes.
The information you received with your first post was correct. The
amplifier in that schematic is cathode-bias and not adjustable.
The common resistor connected from the output tube cathodes to ground
is fixed and determines the bias on the output tubes. My guess is the
adjustable resistor on the phase splitter would be set for lowest
distortion with an output a few watts.
Again, I believe you are showing/talking about two different
amplifiers?????.
