Got a friend who just picked up a used Marshall DSL100, but he says it has a low frequency hum coming from it. He's swapped out both the preamp tubes and the power tubes with no luck. Thing is, is that he says it's basically intermittant and will stop from time to time. I'm hoping that it's not going to be his OT, so just looking for other possible causes. Any ideas?
