Epiphone Valve Standard

[Tiny_Daddy]

This amp just buzzes. No other sound. Volume pots have no effect. I suspect it's the DSP board which I would just as soon bypass. Anyone got info or a schematic?

Will this help?

Yes definitely, thank you.

I has the same issue 3 years ago with a Valve Special. The OT was bad. I thought it was the DSP board at that time as well but it wasnt. Hope this helps

That first op-amp was railed. A new one fixed the amp.
