Check all control voltages:
Also check the connections and component values going into pin 13. R4 should be 1.5M and should connect to +12 V. R2 should be 470R and connect to ground.
If all those connections and voltages are good then it’s a matter of getting the scaling right. R3 (connected to pin 1) should be 24k, R5 (pin 2) should be 5.6k, RV1 (TRK trimmer, between R3 and R5) should be 10k.
For tuning, it’s best to have a scope, frequency counter, or an instrument tuner that tells you frequency. Lacking those you can do your best with any tuner. Set both the TRK and HFT trimmers to the middles of their ranges. Put 0 V and 2 V alternately on the V/Oct CV. These should be accurate voltages or at least have an accurate difference of 2.000 V. The resulting pitches should differ by 2 octaves; in frequency terms, the ratio of the two frequencies should be 2.000. If not, change the TRK trimmer and check both voltages again. (Both frequencies will change, but it’s just the ratio you need to pay attention to.) If the frequency ratio is going in the wrong direction, change TRK back the other way. Keep repeating until the frequency ratio is 2.000 (or the tuner says it’s as close to 2 octaves as you can get).
Then put 3 V and 5 V in and do the same thing, but this time use the HFT trimmer to get the frequency ratio to 2.000. After that go back to 0 V and 2 V and do it all again from there, with the TRK trimmer, then 3 V and 5 V with the HFT. It might take two or three times through the whole routine before everything’s set.
If you hit the limit on either trimmer and can’t get to 2.000 ratio then there’s probably a bad connection or incorrect component value. Check those again.
