I did check the 3 resistors around the zero adjust pot, they are good.. I haven't switched the 12au7 tube but it does test good on my tube tester. Do you think I should try another even though it tests good? The diode is a silicon diode.
My manual doesn't say anything about switching 2 wires so im not sure which ones they would be..
I changed c6 cap, the rest tested good.
Maybe I could just replace all the caps and resistors but that wouldn't really be troubleshooting it and I could probably get another one for what that might cost..
