Yamaha CS80

I think the resolution of the one-turn trimmers is fine enough to 
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)...
