Just got an Ampeg SVT-4 and I have it mono bridged into a 410HLF. I put the amp in a rackmount case with conditioner, tuner. So at first band practice it would cut out periodically. There would be no sound whatsoever for a minute or so. Checked cables batteries etc. I know that there are vents on the back and sides, but it got really hot to the touch. Could it be overheating? Its made for a rack so....?? Any help would be greatly appreciated!
