I hear the trafo in the speakers.. (just a little) and when I touch the plug of guitar cord I hear a BZZZ.. (just a little) if I plug a guitar I hear the sound but I have to put my head into to the speaker to hear it ;D .. everything seem to be wired Ok.. the tubes have a normal glow... no smoke etc etc.... He do this in every settings..
