would your vco chip be the more stable version or the original?? I had to add a diode for the newer IG00153 vco chips when I upgraded? all 16 m boards... can the older be dropped in (I have 2 spare cards) or do I have to remove the extra components?

? My guess would be you killed the IG00153 VCO chip. Try swapping it to another voice to confirm. I have the chip in stock if you need another one.?
