Yes Marcel and Clovis is a really interesting design. The design I'm thinking of uses the garter circuit to balance the tubes. I can't have a shared cathode resistor for the garter circuit to work, so it's a PP stage rather than a differential stage.
PP amps usually require a cathode bypass cap for full power. By putting the cap returning to the cathodes, I don't think I'd need a cathode bypass cap, plus they block any DC on the transformer. The thought is to have a really balanced PP stage, with minimal capacitors, and taking advantage of no DC, unbalanced or not, on the transformer.
No telling what it will sound like, it's just an experiment I want to explore. I haven't seen a schematic like it before, and neither have my local DIY friends, so thought it might be interesting. If it shows promise, I will release the schematic to the DIY community. If it sucks oh well, I'll just drop back and punt to something more proven.
