I have a Model 10 that has done the same. When this happened to my amp I had just powered it off so I could change cables. The amp seemed warmer/hotter than usual before I powered off. When I turned it back on the light on the amp came on but no sound. I checked everything in the system and it was definately the amp that was the problem. I checked the breakers on the back of the power supply unit (no fuses) and they were all good, none of them had tripped. What I did to "fix" the problem was to powered down the amp and then unplugged it from the wall AC. I let it sit overnight to "cool" off and crossed my fingers . The next morning I powered it backup and it worked fine, music again! Not sure why this happened but it hasn't happened again. My guess is that the amp unit overheated and thermally shutdown.
Jeff Rowland Amplifier Help
I think I blew a fuse on my Jeff Rowland Model Ten amplifier and can't locate where they are. The manual doesn't address it and Jeff Rowland is closed until Monday. Any Rowland owners that can help? Everything else works fine and I have isolated the problem to the amplifier. It lights up but no power, thanks for any help.
