Continue preparing the PC board by removing solder from all 22 in-line socket holes. Once this is done, you are ready to install the UF-3.
With the input panel facing you and the component side of the UF-3 board facing away from you, carefully insert the header pins of the UF-3 fully
into the socket holes. Turn the assembly over and solder the UF-3 in place. Make sure all the header pins are well soldered. Visually inspect for
cold solder joints and verify that you have sufficient clearance to re-install the ribbon connector on the top side of the assembly. Finish by trimming
the UF-3 header pins as required.
Reconnect the ribbon cable to the input board connector. Press the locking clamp wings of the connector closed. You will feel them snap onto
place.
If you need to make any adjustments to the UF-3 settings or if you need to record them, do so now, because the UF-3 will be inaccessible once
the input panel is re-installed into the amplifier chassis.
Carefully reposition the input board/UF-3 assembly into the amplifier chassis and secure it by fastening the two mounting screws. Make sure
the screws are tightened snugly, but do not over-torque them. Re-install the upper blank panel.
Installation of the UF-3 is now complete, and the amplifier is ready to be reinstalled into the system.
