1: The motor speed potentiometer is 1.5 kΩ (assuming the motor used is Mitsumi M25E-7; if the optimal

adjustment range is not obtained using a different motor, add a fixed resistance).

2: RML = motor load correction resistance

3: Connecting the preamp off pin to +VCC turns the preamp circuits off.

4: Connecting the motor forced-on pin to +VCC turns the motor on (no control).

5: in circles are pin numbers for a DIP-30P package; numbers in parentheses ( ) are for an SOP-28B

package.

6: In the DIP-30P package, pins 15 and 16 are NC.

7: Ca is a 100,000 pF capacitor used to prevent oscillation of the 1/2 VCC amp circuit.
