Thanks for your thoughts Al.
I suspect my next build - which has a 6C6 pentode input directly coupled to the output tube - will have very high gain. Even when bypassed the plate impedance is so high that the plate R essentially sets the output impedance. So, perhaps I could experiment with running no cathode bypass capacitors... it would lower gain and increase plate impedance, but this may not be an issue. Maybe I should look into that?
