Buzz in my Will Vincent amp

Hello, I have a hum or buzz in my Will Vincent amp. It does not increase when I turn up the volume. Thanks, Cory in Reno
Stupid question but, have you tried contacting Will?
Is it a mechanical humm/buzz, not through the speakers? if so, it could be some dc on the power line or it could be that the xformer hold downs need tightening.
Have you already isolated the noise to the amp? If not disconnect the amp from the preamp (leave it connected to the speakers), put short plugs in the RCA's, and turn the amp on. If you still here the noise, it's coming from the amp. If not, then you might just have a grounding issue.
I have email Will Vincent on an other issue but I can't find his email now, Thanks
