Oh, the amp works beautifully. Brings a man to tears!
But what baffles me is that many transformer designs (including the 3B Super100) have PT's which pump out some 550V+ for the same current.
That said, there's something funny about how this thing "delivers". I had some time with it with the preamp at 7 (remember, no master V) and a Strat (that's it lol). There's something about how it delivers this sorta strained-out current out of the power section, which is only slightly further restrained by a low-ohm choke. BUT! I think there's a lot of voltage sag under a fair load. So, in a flash, as you're about to seemingly drive the amp into oblivion, B+ drops, and that chokes kicks in and cleans it up. BUT!!! On top of that, there's this constant drive and grit thanks to the higher voltages down the line in the preamp when idle. So, in the middle of a mid-rift crunchy bit, you can drop this clean deep E out of nowhere!
I don't know if that makes any sense... It's indescribable...
So, I believe there's magic in the transformer. But how does that voltage doubling work? Are there other documented examples of this practice which I can study?
