Your bias reading should be in the 13-15 mA range PER TUBE. Any hight than 15 or so risks meltdown. The bias pot is the little pot that has a lead running to pin 5 of your power tube. I remember it being the the one closest to the fourth connection from groung on the board. By the way, JJ's DO sound nice. I'm using them in my 2-10 65 every week-sound great. You really should re-cap since it's now 20 years old. I'm not one to say hard and fast that they only live so long , but MM transformers are just NOT to be had so a little preventive work will only save you in the long run. By the way, I know I will start a thread of BS here but I DON"T like the idea of raising the board up to solder on the back side of a MM PCB. Clip the damned things long. wrap them tight aroung the stub and solder them quick. You stand a much better chance of mucking up the boards if you try to turn them over and solder directly to the board and those boards ARE over 20 years old now.If you wrap the stub ends so they are tight before they are soldered, they aren't going to give you any problems. There's some argument material. Mike.
