All,
In trying to calibrate the CS50 and I have a persistent 6.5V at the TU point on the KAS board. Neither the trim pot (VR11) on the SUB board nor the pitch control knobs have any effect on this voltage. The only possible culprit I can identify is the 4558D on the sub board. Is this correct, or are there other components I should look at? The YM26700 seems to be down stream and is dividing this 6.5 up as it should.
Lots to learn!
