yesterday i bought a used 800RB from GC. After taking it home and finding it didnt turn on. (They claimed i couldnt try it in the store cuz it didnt have a power cord), i checked all the parts and found it had a blown fuse. the amp says it requires an 8amp/125volt fuse, however the blown fuse was a 10amp/250volt fuse. This worries me because GC seems to have sold me a broken POS. I shouldnt have bought it but it was such a good deal for 350. Oh well, any ideas of what else it could be?
