Buffer switch
SW1
marks the input buffer switch pads (see bottom left of the PCB image on the previous page).
Notice it is in the same shape as a DPDT switch so it should be easy to solder the wires to the switch.
Pots
We can now continue with the pots. Again let’s start with the most difficult one,
P3
the Speed pot
(C100k DUAL). Bend the bottom 3 pins carefully so they are flat. Use some leftover lead wire to connect
pins 1,2,4 and 5 together and then attach wires to pins 1,5 and 6 like this:
Connect the wires to P3: wire 3 to pad 3, wire 6 to pad 6 and wire 5 to either pad 1,2 or 4,5.
Next we connect P2 and P4. These are standard pots so all you need to do is connect the pins in the
right order. In the pictures below you see the pin numbering of the pots. If you look at the pads of P2
and P4 you’ll see that pin 1 is marked as a square pad. Solder the wires accordingly and it is always a
good idea to twist the wires together to have a sort of extra shielding against external noise.
