Hi, I've got 2 amps I'm trying to get a value on. Any guesses appreciated. 1 is an older SWR Redhead, 240 watt model. Everything works fine and it shows wear from age but isn't beaten up. 2 is a bit trickier. It's an Eden Traveller 400 made 11-05-2001. It's also in good shape with one major flaw. It cuts out sounding like a bad cord after a few minutes or up to an hour. It's not the cords and it won't do it at my house or at the tech I took it to. So it would have to be bought by someone with the confidence they could find and fix the problem. What do these go for without the problem and how much of a hit would the issues cause in the price? Thanks.
