Bought a barely used svt-cl in late 2018 and had no problems with it until earlier this year. First, once when I was playing the volume suddenly drops significantly and most of the lows cut out. The sound could best be described as weak and distant with some fuzz/hissing. No squealing or popping however, and turning the volume up or down did nothing. About three months later I plug in the amp, it turns on but no sound whatsoever this time. I've replaced the fuse, but still no sound, so it seems a blown fuse wasn't the issue. In the three month interim it sat untouched except for a 1000 mile road trip that was definitely bumpy at times, but the amp was very well secured and encased in about a foot of padding all-around. Prior to these issues it was working perfectly. Anybody out there have any ideas? I am no expert on amps so am basically at a loss at this point. I'm on a budget and live a good distance from anyone who could potentially repair it so I would prefer to do it myself if possible. Any input is much appreciated.
