Is any hum at all tolerable?

Two more things to think about. One, the connection of the volume control center terminal to the first AF amp can pick up a lot of hum and is sometimes a shielded wire or the coupling cap has a shield around it. Two, I have seen filaments in pre-amp tubes in guitar amps running on full wave, filtered DC to keep cathode to filament coupling at minimum.
