Members misterhinkydink Posted February 22, 2008 Members Share Posted February 22, 2008 Thanks misterhinkydink, and yep the amp is a blackline Magnovox era SVT. What about the 12BH7 tubes though, I couldn have sworn I read somewhere that they arent regular preamp tubes but are instead driver tubes and that they, much like power tubes, must be rebaised when you change them in an SVT(and that SVTs are different in that aspect from most other amps) Don you know if this is true or not? No, you can't and don't need to bias them. Link to comment Share on other sites More sharing options...

Members ministryoflower Posted February 23, 2008 Members Share Posted February 23, 2008 Sounded like a little baffle buzz goin' on on top of your tube "noise".......just play and press your hand against the face, in the center..till it stops then drive a couple screws in.....
