Thanks for your advice on this, in particular about triode operation. I have built several amps inc 6L6GB/C and mention them below, but certainly don't expect anyone to dig thru all that. :) The plate caps are sort of the whole point of this build. :)
I once made a preamp around a beautiful cast alloy Vol knob from a 1948 EH Scott amp.Seems like another way to treat screen voltage is with a 15H 40mA choke, instead of resistor. Unfortunately, R is high in those chokes.
I could do screen regulation; I have room for OBx type tube regulator, since I'm doing this old-school. They will handle the current but not sure about 250-300V.
Researching screen regulation on this august site shows lots of fights and opinions. Consensus is rare. But I guess that keeps it interesting. :)
Thx
