Have you checked your electrical service? What's the voltage? What's the power factor?
Heat heat and more heat??
My Jeff Rowland model 8 amp seems to be giving off more heat than I can ever remember. The sound still seems great, but the amp gets hot quicker than I ever remember ( heats up the room quickly!) and it is still warm even after several hours after shut down. Any ideas as to what's going on? Is it time for a trip back to Mr.Jeff?
