1.
Identify the 18 AWG white wire that connects to the LEFT channel red binding
post. Twist the conductor strands tightly, and insert the wire into the LEFT
Channel OUT eyelet from the solder side of the board. Solder it on the component
side of the board.
2.
Identify the shielded cable that connects to the LEFT RCA jack. Tightly twist the
conductors of both the drain wire and the center conductor.
a.
Insert the drain wire from the solder side of the board into the LEFT
Channel INGND eyelet. Solder it on the component side.
b.
Insert the center conductor from the solder side of the board into the LEFT
Channel IN eyelet. Solder it on the component side.
3.
Identify the 18 AWG white wire that connects to the RIGHT channel red binding
post. Twist the conductors tightly, and insert the wire into the RIGHT Channel
OUT eyelet from the solder side of the board. Solder it on the component side of
the board.
4.
Identify the shielded cable that connects to the RIGHT RCA jack. Tightly twist
the conductors of both the drain wire and the center conductor.
a.
Insert the drain wire from the solder side of the board into the RIGHT
Channel INGND eyelet. Solder it on the component side.
b.
Insert the center conductor from the solder side of the board into the
RIGHT Channel IN eyelet. Solder it on the component side.
Installing Amplifier Modules into the Chassis
Be careful not to flex the chassis. It’s a bit “squishy” with the top off, but becomes quite
stout once the top is installed and screwed in place. You may want to place a towel on
your work surface to avoid scratching the paint as you complete this section.
1.
This step can be a bit messy, and is considered optional. Completing this step
assures the maximum transfer of heat into the chassis. You’re also likely to smear
white thermal compound on the inside of the amplifier as you set it into place.
We’ll leave the choice up to you (a little more available output power versus a
little prettier insides of the amp). Spread a thin film of thermal compound on the
1/4” wide ridge of the heatsink (the side with four 6/32 mounting holes).
2.
Fit the amplifier/heatsink assembly in place and secure it using four black 6-32
3/8” screws inserted from the bottom of the chassis.
Transformer Preparation
The directions in this section cover 120 Volt wiring. For 240 Volt wiring, you’ll need
the V240 kit. This kit has the parts and directions to wire the transformer for 240-volt
power. The kit builder must supply a country-specific 240 Volt power cord.
Locate the 5” long black and white 18 AWG wires with FASTON connectors pre-
installed on one end. Also locate the 3/16” diameter (clear) heat shrink tubing. For 120
Volt

wiring, the FASTON and toroidal primary wires will be connected as shown in
Figure 42.

For 240 Volt wiring, see the directions that come with the V240 kit.
