Is it correct to say that since all the tubes will see different loads, it may be that they will behave/react/sound differently on the nether end of the same source, or, as you have said, there remains the possibility of variable "blow-back".

The tubes will be loaded differently slight. The Fundamentals channel will be 3dB idler then MF channel and tweeter will be even 6dB more idle. However I do not see it as a problem, in fact I consider even to drive the HF channels with up to 1W less plate dissipations…

But I'm guessing that you already came up with the 1,000 uF value in the supply's out links by listening?

Nope I did not. This is a purely blind guess in order to let choke do not “see” the plate and transformer.

Why is it hard for me to picture unregulated supplies?  I am used to seeing more isolation per tube, and/or per tube tailoring, depending on OPT/load.

Setting the plate loading will be done by transformers. I do not see needs to preserve any specials power souses isolation between the tubes. Do not forget: they are the stages of the same right or left channels. Also not of them will be handling any stressing LF of power and they will be in very “gentile” mode, band-passed at line level. Well, it is not the I’m trying to educate you – I rather am trying to figure out for myself what the hell I will be doing….

I am thinking of an interesting PS link I will try to locate.  It is for a multi-staged amp, but is an interesting "tank", with diodes, no caps in line, with a "stacked" ground plane.

Please find it. At this point I opined for any idea. I even think to drive it with some kind symmetric regenerator since it will be juts HF… Who knows….
