1. From the DUT of the PCB insert and
2. Solder the 3 surface mount ceramic
3. From the component side of the PCB
4. Two values of current limiting power
5. Insert the electrolytic capacitor into
6. From the circuit side, push spacer
7. Apply TW05 thermal washer to the
8. Use #14 sleeving to insulate and align
9. Mount amplifier to heatsink using #6
10. Install components as needed. Ex-
11. Insert amplifier pins into cage jacks

solder the 12 cage jacks. 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.
capacitors to the component side of
the PCB.
insert the terminal strip. Solder from
the circuit side of the PCB. Be sure that
the GND terminal hole in the PCB is
fully filled with solder.
resistors are supplied. 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.

solder from the circuit side making sure
to fill the mounting holes with solder.
grommets into PCB until fully seated.
Grommets will snug when screws are
inserted for heatsink mounting.

at least 2 opposite pins of the amplifier.
screws and nuts. Torque the part to
the specified 8 to 10 in-lbs (.9 to 1.13
N*M). Do not over torque.
ternal connections may be soldered
directly or standard banana jacks may
be soldered to the large pads at the
edge of the PCB.
