Wiring st-35 clones as monoblocks

for the DIY ST35, the Dynakit and every other PP EL84

Let me get this straight...

Are you talking about still using two output transformers per amp (kind of like how some of the old amps could be switched to mono mode)?
Or do you mean connecting/paralleling all the outputs together (like phase) and using a 4k OPT?
I think you mean the second one. We just want it to emulate a parallel PP circuit. I did wire this circuit up one afternoon and had no luck. Thinking back, I probably needed to tie both halves of the 12AX7 & 12AU7 together (according to phase). Basically there were major stability issues and this makes sense to me now. I'll have to fiddle with this sometime and share my results - I think this is worth while.
