Hey Guys,
Just finished a Stout Reverb and looking for some help on quieting the amp down. I've got a significant amount of hum with the amp at idle with no signal. Gets louder as you increase the volume. If I short the Reverb circuit it eliminates most of it. Reverb tank orientation has some effect on it, but I wasn't able to eliminate the hum by orienting differently. Any suggestions?
I'm mainly a Princeton Reverb guy. I've been told that this hum is normal for a Marshall circuit but I won't accept it.....haha
