My 2466 has started to develop, for lack of a better word, a "HUM". Actually a bit more of a buzz, than 60Hz electrical hum. Anyway, I'm thinking its a bad power tube (please weigh in if you think otherwise), I'm on a budget and Guitar center has GT brand KT66 quad for $139. Has anyone tried these? Also, they have 3 levels of tube. Not sure what that's all about. Thanks
