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 !

Victor has been trouble shooting it for a week, asking me to jumper the amp's inputs.. I did with no success, I jumper'ed all three pins and only pin 2/3

No success, have not heard back after my last email..maybe he is on vacation.

Anyway, is on both sides of the amps, meaning both speakers are buzzing equally.

Jfrech: I also hear it about 4ft away .. still, I don't think that this is normal...I maybe wrong, if it is, I bought the wrong amp.

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

would this thing be working if it had a blown fuse... where should I be looking.. I do recall having extra fuses in the box..

thanks

Hey Mejames, I have heard that, but there is no issue with that as far as I can see.. the buzzing still happens when the components are unplugged

thanks
