fit more easily into the socket. Do it a little bit at a time, as it’s kind of annoying to have
to bend them back. Before you install them, double check the orientation of the IC’s.

Mount the Input Selector PCB
Insert the RCA connectors on the input selector PCB through the accompanying holes in
the back panel. Wiggle the board until the jack insulators fit through the back panel holes
and the 4 PCB mounting holes line up with the 4 standoffs in the chassis.
Insert a #4-40x1/4” Phillips SEMS screw in each of the 4 mounting holes. Make the
screws snug, but not too tight.
Test the Input Selector PCB Power Drain
Here is the input selector power drain test procedure:
1. Connect the IEC power cord to the PR-102 and the AC mains (wall socket).
2. Switch on the AC power.
3. Measure the DC voltage on the input selector TB13.
a. The voltage from POS12 to GND should be +12+/-0.5 Volts.
b. The voltage from NEG12 to GND should be -12+/-0.5 Volts.
8. Disconnect the IEC power cord and switch off the AC power.
