They have changed a bit since then, and then a new one got made.
the amps: cascaded diff amp/LTP stages( 6SN7>>6BX7 ) to PP KT90's riding a Dynaco A441. Configured in pentode mode with cathode feedback using the tertiary winding.
B+ is ~380, and the finals are idling at 110 mA for Class A operation. Choke input PS with GE motor-run caps.
I put a bit on the new ones at the link. I have gone DH for the time being.
regards,
Douglas
