thanks for the reply I think i might have been stupid enough to have switched the rotary switch while on. I would still need the correct 2,5amp anything lower or higher wouldn't work would it? Ross

I recently bought a bemaster 4000 that worked when tested with my beovox 3800s. After changing the voltage output i managed to blow the fuses Is it likely that that channel is short circuiting or likely that changing the voltage output has blown the fuses? Also where do i find the correct fuses for the 4000? look forward to a reply many thanks Ross
