If I were to buy this amp I would want to redo the entire chassis and salvage what parts I could. Is the chassis even a standard size? I doubt it, which makes the cab not very valuable, either. If you really want it that bad then offer what the parts are worth to you: Tubes, Transformers, Speaker are the major costly components. ( Does it even have a good speaker? ) This is the kind of amp I list on ebay because you have no idea how much value it has to somebody. $675, though - This guy is dreaming! It isn't worth a third of that..... unless..... It just might have a tone to die for and you have to have it.
