Walter,
I swapped after the 150k. I went right to pin 2 of the 6u8's and switched it there... and yes the hum moves over to the other channel...
I was actually hoping it was in the the output section -lol, as it's easy to get to, more simple and easy to understand. The pre- section is cramped and now lots of controls and pots are in the mix.
So I guess I work backwards from here, and keep swapping until I hit the right section or component? Is there any way to use a scope to trace it back?
thanks
Jeff
