I recently had the power transformer in my amp (a marshall jvm 205c combo) go out. I bought an upgrade transformer from mercury magnetics, wired it in, and I am still getting no sound out of the amp. The board appears to be perfectly fine. Does anybody have any idea what might be wrong?
We cannot possibly troubleshoot the amp effectively for you here in a thread. You need to have a tech check it out in person for an issue like this.
I kind of figured so. I am having trouble finding a place around here that repairs amps though
