I have a Carvin Nomad and it started making a noise in channel two (dirty channel) only. It sounds kinda like a helicopter in the background, but otherwise plays ok as far as sound goes. It is dead quiet as far as amp noise on channel one (the clean channel) and sounds great. I checked tubes and even swapped with known good ones with no success at eliminating the noise. However, I found that if I set the impedance switch in the back of the amp to 16ohms the noise goes away and the amp plays fine. It has a single Celestion Vintage 30 rated at 8ohms installed in it.
I know it's a long shot, but, can anyone steer me in the general direction as to what may be the cause of this noise? Hasserl?
Thank you!
