Building steps

1. Get all the parts out

2. Solder the power header

3. Solder the protection diode, mind the polarity

4. Solder the IC2 regulator and the 1Kohm resistor

5. Solder the C1, C2 and C3 electrolythic capacitors, mind the polarity

6. Solder IC1 drum chip, mind the dot is pin1, lower left corner, square pad

7. Flip the board over and solder the slide potentiometer

8. Solder the thonkiconn jacks

9. Solder the alpha rotary potentiometer

10. Solder the trigger protection diode, mind the polarity

11. Mount the panel and fasten the jack nuts with your fingers. DO NOT USE A TOOL!
