Hello! Newbie here. Been playing a Sunn Beta Bass Combo for quite some time now. Last night in the middle of playing, the sound just stopped entirely. I still had lights, but no sound. I turned the power switch off, unplugged it, plugged it in to a different outlet just to check, and now, no power at all. No sound, no lights, no...anything. Does this sound like a transformer issue? Taking to get checked out later today, but I am basically just curious to find out what people think. More than likely an expensive fix? Any ideas? Thanks a bunch.
