Bogner Uberschall - Buzzing sound - Problem?! Help! - Video.

[guitarslayer]

So I turn on my Bogner Uber today and upon flipping the switch to standby the amp started making a buzzing sound from what appears to be the left side of the amp if you are facing it. What could this be? Is my Tranny shot? Can tubes make a sound like that? I'm afraid if I run it like this I will ruin the amp or damage it in some way. If I bring it to my local tech, they want $95 an hour bench fee just to diagnose. Any help would be greatly appreciated. Heres a video showing the buzzing, you may have to turn your volume up a bit.

sounds like a bad heater on one of the preamp tubes. Have you done a visual inspection? A tech at $95/hr is on the high side but if your not comfortable with pulling out your amp and working on it then I suggest taking it to someone.

I would send an email to Bogner and link the video in the email. Charlie has always been quick replying to my emails or answering questions over the phone.

Swap out the V1 pre amp to start....
