Dave,Be nice to me.
NEVER EVER ask me to explain things up here, my detractors will go wildly amuck !! :-) OK :
(1) It sounds good because it bucks and boosts symmetrically around a zero point.
(2) It also sounds good because it is working, in motion, so the speak, producing a little AC, we call it low-level hum.
WHAT WHAT !!! A percussionist in the orchestra does not hit a gong, at the precise point in the score where it is called for. NO, they lightly tap it to get it moving in advance, ..... THEN they WHACK it good !!
A dead quiet DC 2A3 filament supply will MISS getting parts of the music off, instantaneous things. The amp will be dead, miss things.
These are "my" two reasons why AC sounds good at 2.5 VAC on a Type 45 and 2A3. YMMV, that is OK too !! My best to you Dave.
