Not sure what forum this should go under, so I'll try here for now. I have a Samson TM-500 powered mixer that I got off ebay. Probably: only the left channel works. That's what I wanted at first because it's 250w per channel, and the speakers I was using at the time were only 150w speakers. Now I have much bigger speakers, so I want to send one output from each channel (fyi, each channel has two outputs), but the right channel is making no sound at all. Should I try replacing the fuses first? If not, what are some other possibility of the issue, and how much should I expect to pay if I have to take it somewhere to get fixed? Any help you guys can provide would be awesome. I know I haven't provided too much information here at all... but I'm hoping you guys can come up with some ideas that will help me narrow down the problem. Thanks a lot.
