1. Remove the base plate from the RC-10 (6 screws on the plate; 1 screw
on the back panel).
2. Add the ferri-inductor between pins 7 and 8 of connector B .
3. Locate connectors J2 and J3 on the AF unit (X49-3010-XX B/3).
4. Add a transformer in each mic circuit.
5. Using double sided tape, secure each transformer to the side wall
of the base.
Time required for this modification is 0.5 hrs or less.
