Most forms of distortions that are meaningful
musically, occur when a power supply lags in
timing the power that a tube is drawing on musical peaks,
and then adds insult to injury while it tries to
recharge its filter capacitors WAY TOO SLOWLY.., interfering
with musical flow all the way.
Most tubes, if run conservatively, are very forgiving
as to voltages-- as long as you stay clear of max. limits
as published for the tube BRAND and BATCH that you're using.
Current-wise, tubes stay very linear as far as reproducing
music goes-- less so if you're obsessing over published measurement
recommendations instead of listening. Amps that are called
upon to run at maximum power levels will stress vacuum tubes
unless they're run at quite a bit less than published
current recommendations. This will apply to all small
amps with less than 10 watts of output power with most
speaker loads and SPL's normally wanted in the listening room.
It is very smart to experiment with these values as long
as both voltages and plate currents are very conservative.
Experiment with speaker loading, and output transformer
primary impedances. You're in for some big surprises.
