a. Remove A18 (05340-60036) and replace with High Stability Oscillator 10544A.
b. On bottom of chassis, secure 10544A as follows:
Place oscillator spacers over oscillator studs protruding through chassis.
(2) Using lockwashers, fasten the two 6-32
c. Install transformer T2 into holes provided. Attach with 6-32 hex snapnuts.
d. Dress the group of striped wires from T2 toward T1 and through the cable clamp next to
the left side frame and then toward the rear of the chassis. Route the striped wires through the
hole nearest to the left side frame. (The hole next to the fan will have
