Try calling Jim at his store. He's still open for business. Actually for another half hour. 7P.M. : (815) 323-0898
Is Bob Carver Still in Business?
I have tried to contact the Bob Carver company on some advice on tubes used with the Black Raven 350 amp via phone, email, and through his latest listed distributor Jim Clark.
No one answers the phone, returns emails etc.
