I have two amps that are in an unworking state...and when I mean that, I mean the light that's supposed to glow green glows red, haha. My question is, is it worth it to try to get these fixed? My brother is only running 1x10 right now (instead of two) because of this and I was thinking I could get it fixed for him for xmas. RF no longer makes the amp he's using to power the 10, and he has a second 10 in an enclosure and waiting in the wings... I'm not an electrical engineer, but is it feasible to fix these things?
