Place the panel face down on the work area
and assemble the speaker to the panel as
follows:
Place the grill over the screws so that it
protrudes through the front panel, with the
openings in the mesh facing toward the bot-
tom edge of the panel.
Place the baffle over the screws with the
black surface toward the grill.
(
) Place one of the 9/16" flat washers over
each screw.
Now, install the speaker. Position it as
shown in Pictorial 10. Place a #6 lock
-
washer and 6-32 nut on each of the screws.
Carefully center the speaker grill in the
opening and tighten all nuts.
Place the chassis such that it rests on the
rear apron, power transformer and filter
capacitor.
(
) Remove the nuts and flat washers from
switch
Z, control X,
and capacitor Y.
Place the front panel in position over the
three bushings and install a flat washer and
nut on each bushing. Do not tighten yet. Make
sure that the leads from the neon pilot lamps
are not caught between the panel and chassis.
Install
the microphone connector at W.
Place the connector through the front of
the panel. Install a control lockwasher, a
control flat washer and nut on the connector
inside the chassis and tighten securely.
