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.
