I just bought an Akai AA -1150 receiver and initially it was near perfect.. however, after a few days of playing it, the protection circuit cut out the speakers (in stereo mode) at 20% volume.. I switched it to Mono and both speakers worked fine at any volume.. I tested the DC offset voltages and they were very low at 9MV.. and that was great. I disconnected each speaker (one at a time) and tested it - the protection circuit didn't cut out the speakers at any volume .. I am stumped at what is the cause. I guess I will just have to remove the power amp board to check the protection circuit components - it will be a big job as the Amp is tucked between the Power supply and the Heat sink and I will have to find a wire wrapping/ unwrapping tool first of course. Any suggestions? thanks
