Problem here. Laney

[JC@]

I have a Laney TT100H than sounds well on clean, but no sound at all on the other two channels. I can hear the relay clicks and the pilot lights light on, but no sound.
Maybe, someone knows where the problem could be. I don't have a schem, btw
Thank you.

Sorry, I just realized I posted this same question a few months ago!
