i have recently picked up a Laney LC50 made in the UK amp . it was used and one of the power tubes is doing the classic red glowing thing. I switched the tubes around to make sure it was the tube and not the socket. was that the right thing to do? and do i need the schematics for the amp in order to be able to correctly set the bias when i get new tubes? Where on the amp do i connect my meter to i check the bias?
btw it has JJ KT77 tubes
