Well, I've cleaned up the keyboard bed (all keys working) but still have some issues.
I am having trouble tuning the poly. I am unable to get anything above an A sharp from C. I have tried v10 and 11.
I have also tried changing v2 but this will not get the voltage high enough (returned to original position).
ic18 has about -6.8 on pins 5 and 6 and about 3 volts on pin 7. Pin 7 on the oscilloscope looks pretty crazy.
I read an earlier post that someone had a damaged track that caused this problem, so will check out tracks again. Any advice appreciated.
Once again thanks
ps switch selection normal.
