I've got a powerhead that I use with a 16 ohm 1x12 Celestion cabinet for the past 4 years. On Saturday, at a gig, I set up as usual, but had no sound through the cab. Since I normally run the main out through the PA, it wasn't a disaster, but the cab is my main stage monitor.
Back at home, trying it out, it does put out an audible signal, but it's really low and it seems to waver some. I plugged another amp into the cabinet and it's working so it isn't the cab. I've gone through all the settings and everything looks normal.
Is there anything anybody can think of that I should try before calling support?
