16. Attach the amplifier to the heat sink with the supplied 4-40 x 1/4” male-female hex spacer. Tighten with a

hex nut driver. Make sure the hex spacers are snug but do not over tighten as this provides no benefit and

may break the hardware.

17. Carefully lower the PCB assemblies onto the heat sink/amplifier assembly until the pins of the amplifier

engage in and are fully seated in the cage jacks aligning the mounting holes in the PCB to the hex spacers.

Use the supplied 4-40 x 3/16” screws to attach the PCB assembly to the hex spacers.

18. Hook up power and signals as necessary. The amplifier is now ready for testing.
