Have you checked to see if there are sources of noise like a worn refrigerator compressor motor or dimmers coincident with the buzzing? What about trying a direct run to the house breaker panel?
Tube amp buzz (amp, not speakers)
Hello -
Almarro a318b makes buzzing sound at random: sometimes it does, sometimes it doesn't, completely unpredictable. The buzz comes out of the amp itself, like a transformer buzz; the sound out of speakers is completely clean.
I'll appreciate any ideas - what causes it, what to do?
