Thanks, Thorsten. I hoped you would post these results - very valuable contribution to our knowledge base. I'm going to save this one.
We had a VALVE meeting yesterday, and listened to Richard Riley's 2A3 amp which uses a 6SN7 in a slightly simpler arrangement - I assume you are doing basically an SRPP with a choke for the upper bias resistor. This is his improvement on my original circuit which had a conventional mu-follower. It's simpler and it sounds better, even though he now has this extra choke (actually the primary of the cheap Allied interstage) hanging by its wires outside the chassis. I believe he is taking the output from the lower tube plate, which has less drive capability but seems to sound better. I don't know if the lower cathode resistor is bypassed - Richard, are you reading this?
