Motorola B12WA recap and mods

[maxhifi]

Does the full wave rectifier raise the B+ enough to require changing the operating points of the tubes? (Specifically the audio output?) is there a meaningful reduction in hum? I would imagine the higher amplitude of 60hz hum would be partially offset by the higher sensitivity of the speaker to 120hz hum, even if the ripple voltage is lower with a full wave rectifier - curious what is the practical outcome.
