ASSEMBLY
During assembly refer to Figure 1 and Figure 4.
1. From the DUT of the PCB insert and solder the 12 cage jacks.
2. Solder the 3 surface mount ceramic capacitors to the compo-
3. From the component side of the PCB insert the terminal strip.
4. Two values of current limiting power resistors are supplied.
5. Insert the electrolytic capacitor into the PCB from the compo-
6. From the circuit side, push spacer grommets into PCB until fully
7. Apply TW05 thermal washer to the bottom of the amplifier.
8. Use #14 sleeving to insulate and align at least 2 opposite pins
9. Mount amplifier to heatsink using #6 screws and nuts. Torque
10. Install components as needed. External connections may be
11. Insert amplifier pins into cage jacks and fasten PCB to heatsink.

Also solder the cage jacks from the circuit side as well, making
sure the cage jack remains flush with the component side of the
PCB.
nent side of the PCB.
Solder from the circuit side of the PCB. Be sure that the GND
terminal hole in the PCB is fully filled with solder.
Select one value (see the amplifier data sheet to learn how to
calculate which resistor will suit your need). Coat the backside
of the power resistor with heat sink compound (not supplied).
Using 4-40 screws and nuts (not supplied) mount the resistors
to the two small heat sinks supplied. Solder the resistor/heat sink
assembly to the component side of the PCB.

the part to the specified 8 to 10 in-lbs (.9 to 1.13 N*M). Do not
over torque.
soldered directly or standard banana jacks may be soldered to
the large pads at the edge of the PCB.
