AR ARS112PS Subwoofer - Hum
Hi,
This subwoofer is not that old and developed a hum, even with no signal going in. It was made in China - you guessed it. Do not have a schematic. Pulled the ckt assembly out. Workmanship is ugly, but do not see anything obvious. The ckt bd smells a bit , but it could be how these things smell :-) There are 2 large caps 63V 6800uF in the PS. Would that be the culprit? Regards, Rich |
