I bought a Onkyo SK10W sub on Ebay (yep first mistake) and hooked it to my
Onkyo TX-SR303. After it is plugged into AC for about two minutes it stops
amplifying. If I unplug and try it again it works another two minutes. I
switched to another subwoofer using the same wire and it worked fine. I
tweaked the crossover with no effect. Am I looking at a new amp board? I
have $63 in it as it sets. Fix or cut my losses?

Thank in advance
