DIAL CORD REPLACEMENT
Replacement of either dial cord in the G-66 re-
ceiver requires the removal of the frone panel. Re-
move all front-panel knobs and the bushing
nuts
from the VOLUME and FUNCTION controls. Then
remove the screws adjacent to the bandswitch and
tuning-knob shafts and carefully slip the front panel
forward.
To replace the band-change cord, proceed as fol-
lows:
a,
Set the band-change shaft to 20 M position and
loosen the pulley setscrew.
Rotate the pulley until it is possible to disen-
gage the spring. Then rotate the pulley in the
opposite direction until the looped end of the
cord can be unhooked.
c. Remove the pivot sctew from the left end of
the cuning drum. The drum may now be
dropped slightly to make the ends of the cords
more accessible.
d. Rotate the dial drum until che cord holes are
below the dial-drum bracket. Remove the
broken cords and replace with cords made to
the lengths shown in (a) of the bandchange
cord stringing diagram.
e. Replace the dial-drum pivot screw, Wind the
cords on the dial-drum pulley as shown in (b).
Rotate the bandswitch-shaft pulley to the pos
tion shown in (c) and connect the looped-end
cord.
f. Rotate the bandswitch-shaft pulley clockwise
and hook the spring as showa in (d).
