If neither channel is operating I suspect either a tube, a power supply issue, a broken mute switch, a selector switch issue, or a volume control issue...
System down. Need your help and recommendations.
I had to move my stereo out of the house and put my Audio Research LS1 on the front car seat for the ride. It was bumpy and now it doesn't work. It lights up. I took the tube out and put it back in but I really don't know what I'm doing. Any help would be appreciated.
