Step 2: Resistors

Step 3: Sockets

Insert and solder the 10 resistors:

100ohm x 1

•

330ohm x 3

•

10k x 1

•

47k x 2

•

220k x 2

•

Optional:

•

◦ 47k x 1 for "-R-"

◦

Note: the spot marked "-R-" is a tweakable resistor. Changing its

value will change the analogue filter. The easiest thing to do is to

install a 47k resistor. A more advanced approach is to install a

socket in the next step and put in a 47k resistor later. Then you can

swap out different resistors for different filter sounds. The photos

show the advanced (sockets) approach.

Insert and solder the sockets:

Observe the notch on the socket, and line that up with the printed

notch on the PCB.

8-pin IC socket

•

14-pin IC socket

•

(optional) 8-pin machined socket for -R-, and -C- x 2.

•

This socket has round pins, not flat "leaf" pins like the other

two sockets. It doesn't matter which way the notch in the

socket points.
