Hello, I also have a problem with the top lane.
Not a lot of sound and saturation ..
I have redone the power supply but have not yet changed the capacitors on the front plate..
Do you think this is the solution?
Thanks a lot

Suddenly got the 250Hz lighting up constantly and no audio signal going thru. Disengaged Audio In then still works as a bypass. Any tips? I probably should just find alternative solutions haha too old of a system.

I have a different problem: although channel 1 and 2 get the same input level, only half of it is output at channel 2 (compared to channel 1). Does anyone have a similar problem or tips to fix this? Thx
