This is my system, receiver wise, and all of them but one needed repair. The SX-434 just needed a couple of fuses, plus a pointer and stereo light, the SX-525 also needed a pointer light, plus the whole main amp board needed recapped and all new transistors including the outputs, then the control amp needed recapped as well, which with markthefixer's help, I got done! Thank you Mark! Then the SX-890 had already been repaired by another member on here. So, I've been having a lot of fun lately :)
