Hello!
I am trying to build a Claus Byrith PP using KT66 instead of EL34. I've google a bit and found some comment said they are interchangeable with re-bias, that should be very easy on this design.
I compare the datasheet of KT66 and EL34, the former use less heater current so no worry on PT and should able to take 440V B+ as well. So really no changes is needed? Would appreciate to have some ideas, thanks.
Here are the schematic:
