The Automatic Turntable

The heavy, precisely balanced platter of the automatic turntable
is protected from damage during shipment by a foam plastic tiller.
which also contains the spindles. To prepare the FISHER Auto-
matic Turntable for operation, the following steps should be taken:

1 - Remove the two large machine screws from the wooden
bracket holding the foam plastic and platter in place, Then lift oit
the wooden bracket,

2 - While holding the platter within the plastic filler, lift the tiller
straight upward until clear of the compartment walls, and place
on a horizontal surface.

3 - Remove the two screws holding the metal brackets, and dis-
card the brackets The FISHER is now ready for final installation
as described on page 5 of the turntable instruction booklet.

The Antennas

There are two antennas already built into the Electra: one
for AM and one for FM. The AM antenna is a ferrite«core loop,
mounted on the Tuner-Control chassis. It will provide excellent
reception of AM stations in almost all cases without the aid of an
external antenna,

The FM antenna is made of GOO-ohm twin lead"-the same ma-
terial used for TV antenna lead-in wire-cut and wired especially
for use as an FM antenna. You will find it stapled to the back of the
cabinet. It will give excellent results on both stereophonic and
monophonic FM broadcasts. except possibly in lringe areas If you
have difficulty with FM reception, consult the ANTENNAS section.
on page 12 of this manual.

Location of Cabinet

Cabinet location may be varied to suit your acoustic and decora-
tive requirements. The Electra is suitable for corner installa-

tion. along a wall, or as part of a room divider, Whichever location
you prefer, be sure the cabinet is away from heat-producing
radiators and ducts. Transistors are heat-sensitive components
which, contrary to popular belief. do generate heat. Because of
this, you should allow a minimum of two inches between the rear
of the cabinet and the nearest wall to permit circulating air to
cool the transistors. This provides the optimum environment for
transistor operation.
