| Tune for lower oscillator – R116 is replaced with 1M-Pot and 220k in series. The lower oscillator can be tuned then. The 220k will prevent bad sound in extreme potpositions. You also can take 2.2 MB-pot but beyond the 1M there wont happen too much. | Tune for lower oscillator – R116 is replaced with 1M-Pot and 220k in series. The lower oscillator can be tuned then.
