1) I'm looking at an ampeg vt40. I can get it for $300 unloaded, but it will need servicing. I'm thinking it's early 70's as it is toploaded. I' not sure what kind of work it needs, it already has a master volume mod done. I've played it once a year or so ago and the amp sounded good except a speaker sounded a little buzzy. It also had handles added to it, where it's a beast to carry. 2) Is it hard to get GOOD parts for this? Ive heard they are rare, and even then you have to find good parts. 3) What kinds of speakers could I get that aren't to expensive? I'm really not sure if these amps are money pits. Thanks guys.
