BAT VK75SE buzz and humming ?? help..

Hello all, received a BAT VK-75SE which by the way is a lovely Tube amp for those that are not aware.

Unfortunatly I have plugged it in and have had a constant buzz since day one.. the buzzing remains even when Interconnects are removed and ground is lifted

I have :

1. Plugged the amp in a different part of the house- No Change

2. Changed Speakers and speaker cable - No Change
3. Changed PowerCord and Lifted ground - No Change

The amp itself is dead quiet, no transformer hum or anything.. could tubes do this ? ..

thanks all in advance !

Marakanetz, thanks... have no idea what you said.. but I presume I need to test the tubes out one way or another ..

I may have a guy locally that can do this..

The unit is not old, I would say within 2-3 yr.. the TUBES, well the box that they were wrapped in said "CCCP" need I say more..

thanks
Matt

Are you using XLR adapters on the inputs? There have been incidences where the adapters are the cause of the hum. Try using a pair of balanced interconnects, See if that helps.

you didn't buy the wrong amp...that's one of the best. somethings up...bad tube, bad component...ground loop...

I'm sure you have checked the fuses. Every time
I had a fuse go I would hear an increase level
of hum.
