Hey guys, so I am currently working on a CR-2020, doing a recap and preemptively replacing "known to fail" tranistors.
So far I've done the preamp and both power supply boards.
On completion of the power supply boards I now have a very loud Hum/Buzzing from my amp boards, this occurs regardless of the coupler switches position. I just find it strange that there's no issues at all with the preamp.
Since everything else works fine am I right to assume my issue is on the board with the main filter Capacitors?
I did all 3 service bullitens, as well.
