You can test the VCO, by checking the voltage at the junction of R107 and R108 the voltage should go up has you go from channel 1 to 40
if it not check the voltage at the Base of Q100 the voltage should go up has you go from channel 1 to 40.
Also check for volts at each side of R102 it should be about 8 volts, I have had R102 go open circuit.
