a yamaha cs-50+UPS

2003-04-22 by Ed Hallborg

Thanks - I guess I'll have to look into this.  So far I have gotten the psu board back together and some of the sad little broken slider caps glued together.  It is working 65%.  All the presets are working, ring mod, lfo, touch, etc.  But the all the Panel functions- vco,vcf,vca are dead.  I think its either something at the power supply again, or possibly related to the broken sliders- cutting off power.  On the plus, I got it tuned yesterday.  There's hope yet... Ed

IF it was an ebay purchase and IF it was insured you can get the EBAY 
purchase price back. Otherwise the repair of a cracked pcb will either 
require a replacement or some patience and creativity. Good luck.
