Good day everyone I am working on my xs4600 I purchased from ebay for repair and having issues. I pulled all the power supply fets because it kept blowing fuses. When I connected the B+ and ground without a remote it powers up. I have been looking for the transistors in line with the remote and B+ but having issues. Perry over at Diy forum has been amazingly patient trying to help. I will post the link for the thread below. Any help would be greatly appreciated.

Re: Xs4600 help
OP sent me the amplifier after several attempts to repair it. Seems like previous owner did some serious damage to the PCB through vias, I had to repair all the vias on the rail caps. Used 3205’s for the PS repaired an open trace (primary to secondary ground), also had to replace several 56/06 in the PWM IC circuit due to damage vias, with new transistors I made sure solder was one both sides of PCB. Replaced damaged power terminal block, shipping back to OP on Jun 20th.
