I have two JJ 5Y3 tubes. I use them in my 5F11 build. One is putting out around 340 VDC to my plates and the other is putting out around 397 VDC to my plates. Which one is closest to what a 5Y3 is supposed to put out? I currently have the 390 V in it and my 6V6's are running around 24 mA. It sounds pretty good. The other one that puts out 340V is obviously much cooler and I can get 18/19 mA by adjusting the bias pot. It sounds good too. Which one would you run if it were yours? I really don't like the 397V on the plates. I feel that's too hot. Am I wrong?
