Question about Yamaha YST-SW015 Subwoofer
Similar problem, maybe inherent to this sub, found wiring diagram ( can't remember where right now) R46 is 150 ohm - 1/4 watt. As informed by many sources - burnt resisitor just result of other fault - on replacement resisitor just smoked it up again. Have tech attempting to separate power supply from amp to locate problem. WIll post result if faulty component is located. Not much of a sub anyway - just can't bear to throw it away for cost of minor component.

Resistor at that range work as a current limiting, look at the power transistors. they are mounted on the heat sink. remove them and check with a meter for shorts.
Look at newark electronic for parts, I have found the parts to be very reasonable
