Harmony 8418 Stopped Working in Amps Posted February 23 I’ve had a Harmony 8418 for a little while. It was working fine yesterday but today no sound is coming out. I haven’t had any issues before. The fuse looks ok & the speaker wires are connected. The 5y3gt is lighting up and gets warm. The 6v6 doesnt seem to light up but it gets warm. The 6sj7 is enclosed so I can’t see if it lights up but it did get faintly warm. Any suggestions?
