RE: 6V6 PP Line Amp/PPP Power Amp Schematics (Kondo HOH-OH)

I have been using a PP 6P14P-EV amp for a while with this external power supply and a similar front end topology to this one. I was lucky enough to purchase on epay 13 NIB National Union 6V6s for $265 recently so will go ahead with plans to build a PP 6V6 amp. This PP 6V6 amp clearly derives its inspiration from "El Cheapo."

Output transformers will be UTC LS-63 and the CCS is from K&K Audio. The top plate will be machined by Front Panel Express and the chassis from Landfall Systems. The 6.3V transformers will be on the amplifier chassis not the PS chassis. Since I have not built the 6V6 version yet, the expected voltages and currents are derived mathematically, not empirically, so may change slightly.

It would be difficult to build a feedback amplifier with transformer coupling.
