This is a good point. Does anyone out there know if you can make the other numbers work. In other words is it possible to make a IG00153 '33' in a synth that has '11's'?

What I meant Mike, was that should an Osc chip 'blow'... you'd more than likely not find another '11' anywhere. If you did find and Osc chip to replace it with you'd just have to use whatever came your way!

I'm having trouble understanding what you mean.. I bought it because it sounded awesome even though I already have a CS80. After taking it apart and going through the calibration routines, I noticed that all of the Oscillators are factory coded 11.
This is the way that I bought it. I didn't modify it or swap cards. I picked it and chose it because it was the most in tune CS60 I've ever heard.

Yamaha's scaling system was all very well and good when these IC's were available in abundance. Nowadays though, I doubt anyone would have the luxury of "picking and choosing" - please do correct me if I'm wrong ... (which I do hope I am...!!)

I've got a Yamaha CS-60 for sale in Chicago, IL. It is from my personal collection. Everything works fine and I have replaced some sliders that were a little bit dirty. It is an exceptionally stable CS60 because all of the oscillator chips are factory selected "11."
In the factory, Yamaha paired up all of the oscillator chips with similar temperature response characteristics. If the heat went up, Yamaha wanted the scaling to go up the same amount with all of the oscillators.
According to Yamaha literature, "Each IC built into the "M" circuit board is ranked and labeled every 5 Degree C according to the degree of change in the musical interval on C1 and C6 affected by the ambient temperature change from 25 to 50 degrees C."
A value of 11 is the best and 96 is the worst.
