Have you seen my schematic? You could substitute the 6n1p with your 6SN7.

Look again. EL34 is triode strapped. Power supply is tube (5U4). No 6SN7. if You are able to do that can try to design your own driver stage or whole amply otherwise You've to accept what community has.

The whole schematic are somewhere over internet, search Michel Leluaux EL3. I have the full article if You are really going to built it.

Ah ok...just replace with a 22-68k resistor! Aim for around 200-225 volt on the plate...and adjust cathode resistor so that around 8mA runs trough 6sn7. et voila.
