JBL PRX518S schematics

[Yeoman]

Hello,

Anybody here have access to the schematics for the JBL PRX518S power amplifier module that you would be willing to share?

I have one in the shop with the typical shorted mosfet pair that I replaced but still does not power up.

Thanks in advance!

You're in luck, i bought only the amp module (faulty) off eBay a while ago, and the local Harman distributor was kind enough to send me the service documentation for it.

Although i should warn you, at least on mine, when i tried to power it up with the four fets from the amp removed, i managed to blow the two IGBT's in the power supply
