I have modded a China 5 watt SE guitar head and I have a constant buzzing background noise sound (when I strum the strings) that I can't get under control. It sounds like something is vibrating with the strings, but it's not a mechanical problem with the speaker or tubes. I've swapped them all to isolate the problem, it does seem to be coming from the amp and I'm running out of ideas now.

Does anyone know the problem or have similar experiences. What could be responsible?

The circuit now is a really good sounding hot Mini Z clone (but with Master Pot) but the problem was already there with the donor amp. Tubes are 1x 12AX7 and 1x EL84.
