    Hey guys, maybe someone here can help me out. I’ve had this JCM 2000 DSL401 for about 8 years, and now whenever I turn it on, it is normal for about 5 minutes, but then has a gradually increasing buzz coming from the back of the amp. Changing the volume does not matter, nor does what channel it is on. Same thing happens even on standby. 5 minutes okay, then a slight buzz that quickly gets louder. The tubes are all lit up, and with my limited tech knowledge I’m at a loss. Any suggestions? Thanks

    Thanks for the link Frank, couldn’t quite narrow it down from that however. I’m thinking of taking it to a tech guy, but if someone here knows a simpler solution or has solved a similar problem lemme know.
