Yamaha CS80

erik, what would the temp code look like on a VCO chip? is this a way to determine an early vs. later chip?

 adjust the oscillators for zero beating by ear (or let's say, 1 beat 
 every 10 seconds, that's 0,1Hz isnt't it ?).
 
 Very important is having oscillator-ic's all with the same temperature-
 code. One of my CS80's has all equal numbers and is immidiatly in tune, 
 there's no difference in 1 minute warm-up or 2 hours warming up.
 My other CS80 has 2 ic's with different numbers, and there I've to wait 
 for about 10 minutes (that used to be 1 hour before I renewed the 
 thermical grease around the diode)...
