The JBL Powerbass PB-12 is famous for having a defective power supply. Someone is selling one on CraigsList that "doesn't power up" for a small $60. The average price paid in the Reviews section was $400, so the difference is large. I saw alot of complaints about the amp dying.



How hard/expensive would it be to replace the amp myself? Would I be able to use a generic amp that meets its specifications, or would I have to find an original made specifically for that sub?
