I'm getting a crackling sound from my Fender Deville that I just bought on Ebay. Seller told me it was 3 years old and it didn't make this sound last night when I tested it. I wonder if I need to replace a tube, but don't know if it is that issue or a short somewhere. The amp is in great condition cosmetically and I don't think it was used very much.
Please advise and THANKS!
