Dodd 120 mechanical buzz?

Amp/Preamp Asylum

Looking for a new Amp or Preamp? If you're after tubes, post over here.

Hello All,

I just bought a pair of the Dodd Audio 120 monoblocks and when I go from Mute to Operate on the left channel amp there is a mechanical buzz (not through the speakers) coming from the amp that seems to be to the left of center mid-amp.

I haven't been able to get in touch with Gary and know he's been ill so I don't want to bug him. Does anyone know what the problem would likely be? Is there a choke or transformer midway back inside the chassis or could it be the output transformer? If it's just a matter of tightening a few nuts I can probably do that myself. If I need to replace a transformer (before it fails) I'd want to know about it. But so far I've not had the bottoms off to look.

In fact, if anyone could send me a pic of the inside of the amp I'd appreciate it.

Any and all ideas are welcome!
