Hold the breadblock down
flush to the PC board from the
top legend side and solder the
metal pins in place. Then, melt
the plastic pins with your
soldering iron to hold the
plastic blocks in place, as
shown.

1. VR1 and VR2 - Before installing the pot
into the PC board, bend the center lead
over to the right lead and solder. Cut off
the excess leads.
2. Install the pots flush with the PC
board. The value may be marked on
the back of the pot. Cut off the excess
lead length after soldering.
3. Place the 3/4” tubing over one lead of
the 1.2k
W
5% 1/2W (red-red-red-gold)
resistor. Postion the resistor as shown.
Solder the resistor from the bottom
hole of C10 to the right lead of VR1 as
shown.
Solder a 1.2k
W
5% 1/2W (red-red-red-
gold) resistor from jumper J1 to the
right lead of VR2 as shown.
Caution:
Make sure
resistor lead does not
short to jumper wire.
