Hi again... after a few failed attempts at grabbing new amps, I'm now looking at what I believe to be a '57 Tremolux with a reproduction cabinet. Amp looks totally stock from the photos I've seen. Not even sure if its been upgraded to a 3-prong cord. The only knock against the amp's originality is both the cabinet and the speaker. Speaker doesn't really bug me, but the cab is an Armadillo reproduction (seems to be of high quality at least). My question is how much does this reduce the value of the amp? And what would be a fair price for an amp like this?
