you might want to try searching on Audioasylum, either under General or Tube Asylum.
I recall reading some interesting stuff there re: tube rectification and it's effects on tube "bias" setting (fluctuation more likely with tube rectification)Some dude had modified am amp to enable him to plug in a solid state rectification device into the tube sockets...
Also, from my own experience (manufacturer hype) AudioPrism Debut I used to own had pretty good bass for an EL-34 based amp, due, in part (according to manufacturer) to the solid state rectification (no tubes used for this purpose).
Then again, I just compared a Tube Rectified Cary to a SS rectified Rogue, and the Cary had stronger bass (but the tubes did fluctuate a bit, however the audible effects of tubes fluctuating by 2-3% are unknown to me).
Anyway, I really don't know. But (this sounds silly) in my experience, the more tubes used for ANY purpose, the better the sound(and the worse off your wallet will be).
good luck.
