Thiel Smartsub SS1

Hi,


My Thiel Smartsub SS1has a problem with the inside amp. I put in signa cable in the LFE out and then the fuse exploded. Its still playing but when I turn the LFE pot open it has a loud hum and the fuse burns again. I need the schematics for repair. If I’m well informed the amp was developed by Parasound. Any thoughts about this?
