Question about JBL PB10 Subwoofer
Generally, if a fuse blows it is indicative of a fault with any of the components. If the fuse is on the AC side, then chances are it is the power supply, if it is on the DC side, then it is the amplifiers side.
I tend to suspect that you cannot find a replacement board. And if ever available from the manufacturer would probably cost just slightly less than buying a new set.
Your alternative is to seek the services of qualified audio technician who is willing to do component level repair. Circuit design would not differ much from basic amplifier hence replacement parts would reasonably be available versus entire PCB.
But then again, you must consider the cost/time of repair. If cost of repair plus downtime would not be to your liking, perhaps your best bet would be to purchase a new unit.
The cheapest alternative would be to do a DIY (do-it-yourself) which would require that you be familiar with basic electronics circuitry & components, use of & access to a DVM and use of a soldering iron.
Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.
Good luck and kind regards.
