john_rut Posted September 29, 2017 Share Posted September 29, 2017 I was playing at band practice and all of a sudden no sound. Power is on and all switches are responding so I figured it had to be a tube. I changed out to my backup set and still no sound. I can see the tubes powering up but still nothing at all. I tried resetting the amp as suggested in the manual and still nothing. Any suggestions on troubleshooting the preamp section or the digital section?
