Product Release 1 Setting Up the Amplifier
5.2 Install the Transformer
NOTE
•
The transformer is very heavy. When moving it, use due caution
and handle only by the lifting handle.
•
The extra piece of wood shipped with the amplifier is the
transformer shim, which was cut to specific dimensions to aid in
this installation.
•
Do not over-tighten the screws that hold the transformer in place,
as doing so may cause excessive vibrations or noise.
•
If you move the amplifier, even if only from one site to another
locally, remove the transformer first to avoid the possibility of
damage.
Procedure 5-2 Install the transformer
Step 1 Position the amplifier on a flat surface, at or near where it is to be used,
with plenty of room for you to work.
Installing the amplifier on a tilt so far that the transformer is cantilevered
or
hangs out to any degree causes the chassis to distort, which may affect
a number of things, from the alignment of screw holes on the top cover to
the band-switch alignment and tension.
Step 2 Slowly move the amplifier and transformer together, aligning the nuts on
th
e transformer with the screw holes on the bottom of the amplifier.

Step 3 Secure the transformer into place from the bottom of the amplifier by
inserting the supplied bolts (1/4/20 ½-inch hex bolts) with ¼-inch
washers through the four clearance holes in the chassis and into the nuts
in the transformer base.
