Mitchelectronics vco

1

I’ve just assembled the mitchelectronics vco. Which resistor do I replace with a pot to lower the output pitches by a few octaves? On my 555 vco I put a pot between pin 3 and 6. Thanks.

None of them. Wire a potentiometer as a voltage divider to control the supply to VIN.

Thanks. That worked a treat.
