Buzzzzzzzzzzzzzz

[racko7566]

Hey guys, I know you have heard every buzzing question a thousand times but heres a new one for me. I tunded on my amp (dsl 100 ) and the buzz is louder than usual. Figured maybe pre amp tube on the way out or bias may have drifted, or maybe my power source since I just moved in an old farm house. Whats happening is when I went to bias the amp I touched my screwdiver to the chassis and it made very noticable static sound through my cab. Does it any where on the metal. Any ideas what this problem is?
Thanks.

Could be a grounding issue...Old farm houses are notorious for poor power properties..

Like Adrian said, it's possible that your wiring isn't grounded (earthed). That's more of an electrician's job than an amp guys

Hopefully it's not, but it seems possible, since you just moved into an old house.
