I know this thread is old, but I'll toss out my experience for anyone listening. I've had the psw2150 for 5 years, a couple years ago it started the dreaded "buzzing" that people talk about, and I just put it away. A couple months ago I read more about the problem, and decided to try the capacitor repair that is talked about. That worked, so if your sub is making a loud buzzing sound from the plate amp, replace the C52 capacitor. This worked for a few weeks, but just tonight it died. It's not that capacitor this time, it's something else. It powers on, but no sounds. The no sound was preceeded by several "pops" while playing, and then one loud one and it was silent. Hopefully this forum can help me out. I have yet to test the driver, but I'm pretty sure it's the amp.

Mine had a trace blown. It was the input to a linear regulator. It was right where the wire solders to the pcb. I soldered 2 wires twisted together (for more copper) from the thru hole where the wire solders to the PCB, to the input pin of the lin reg.
