*3 x 500k pots [31VQ505-F] SYM*, SMOOTH, SPACING
6 x knob covers
1 x 330 ohm resistor [291-330]
4 x 1k resistor [291-1k]
1 x 2k7 resistor [291-2.7k]
2 x 100k resistor [291-100k]
5 x 220k resistor [291-220k]
1 x 470k resistor [291-470k]
2 x 1M resistor [291-1M]
2 x 1uF cap [140-XRL25V1]
2 x 10uF cap [140-XRL25V10]
**1 x 100uF cap [140-XRL25V100]
1 x 0.01 cap [140-50Z5-103M]
1 x 330pF cap
2 x IC sockets [575-993308]
1 x 4558 opamp IC [513-NJM4558D]
1 x 072 opamp IC [511-TL072IN]
1 x round yellow LED [351-5500]
1 x LED clip
1 x superbright red round LED ("red LED")
1 x CdS cell: <5k light, >500k dark (Jameco #202391, or electronic-goldmine #G15177)
**1 x 7809 voltage regulator
**1 x power supply jack
1 x stomp switch 3PDT
2 x Si Diodes

* for point-to-point boards, or if doing FINE instead of SYM on the PCB, replace a 500k pot with a 10k pot. Also, omit the 2 x Si Diodes.

** if using a powersupply, then include these 3 items. If using a battery, include a battery snap instead of these 3 items
