DIAPHRAGM AND
COlL ASSEMBLY REPLACEMENT
The assembly is a delicate part. Do not
touch the voice coil and bobbin, or allow
it to come in contact with the work sur-
face, tools, etc. If the assembly is placed
on the work surface, rest it on the dia-
phragm with the voice coil upward.
8. Assemble the new diaphragm and coil assembly
to the magnetic structure with the coil facing
the magnetic structure. Locate the three small
holes in the diaphragm and coil assembly over
the locator pins in the magnetic structure. The
three large holes in the diaphragm and coil as-
sembly will line up with the screw holes in the
magnetic structure.
9. Assemble the horn to the magnetic structure.
Magnetic attraction between horn and
magnetic structure will cause the horn
to "jump" to the magnetic surface; use
extreme care to avoid crushing the
diaphragm.
a. Type
I: Position the large holes in the horn
over the three mounting holes in the mag-
netic structure, making sure that one straight
edge of the horn flange is aligned with the
straight edge (between solder terminals) of
the diaphragm and coil assembly.
b. Type
II: Position the threaded holes in the
horn over the screw clearance holes in the
magnetic structure, making sure that one
straight edge of the horn flange is aligned
with the straight edge (between solder ter-
minals) of the diaphragm and coil assembly.
10. a. Type
I: Replace the three screws and 8-32
x 11/32" nuts and tighten them securely but
do not overtighten.
b. Type
II: Replace the three screws and tight-
en them securely but do not overtighten.
11. Reassemble the high-frequency speaker into
the speaker enclosure and reassemble the
Column.
Nameplate
Should it become necessary to replace or re-fasten
the front-panel nameplate, be sure to use a heavy-duty,
weather-resistant adhesive.
Goodyear PLIOBOND or
equivalent cement is recommended.
