The CS-8000 power supply uses a few components that must be obsolete. One is the Fairchild power switch(FPS) KA5L0565R (5L0565R) and the photo-coupler PC-17L1. Trying to cross reference the parts I find nothing. Found one sourse in England that has some, but they are proud of them (pricey). The FPS was introduced in 2004, so you wouldn't think it was that scarce. Has anyone had any success in finding these, or know of a power supply board available? Thanks.Ed.
