INTRODUCTION
The Heathkit Model AR-14 FM Stereo Receiver
contains an all solid-state circuit that provides
high quality reception of standard FM and FM
stereo signals. Each of its amplifier channels
also has input connectors for mono and stereo
phonograph and auxiliary signals. Tape Out-
put connectors are also provided. The mode
of operation (FM, Phono, etc.) is selected by
the Source switch on the front panel.
All controls (Source, Treble, Bass, Volume,
Phase, and Tuning) are located on the front
panel. The Phono and Auxiliary input connectors
are located on the rear panel, along with the Tape
Output connectors.
The FM Tuner circuit contains a preassembled
and prealigned FM tuning unit. All critical parts
in the other FM circuits have been aligned at the
factory, so only a few simple adjustments are
needed after the kit is assembled. These simple
adjustments can be completed without using
instruments.
The solid-state amplifier circuits provide you
with
high-fidelity sound reproduction at low cost.
Both amplifier channels have a frequency re-
sponse of ±1 db from 12 to 60,000 cps at full
power output. The transformerless audio output
circuit insures minimum phase shift, widest
response, and lowest distortion. Tandem con-
struction was used on the Bass and Treble con-
trols so each channel can be adjusted simultan-
eously. A concentric clutched Volume control is
used for independent level adjustment of each
channel. A speaker defeat switch allows the
speakers to be turned off when stereo head-
phones are plugged into the convenient front
panel jack.
The use of the latest type of output circuit
eliminates the problem of severe transistor
damage that occurs in other equipment when the
output terminals are accidentally shorted. The
output stage in this amplifier will withstand an
accidental shorted output for periods of up to
30 seconds with no damage to the transistors or
other components.
This receiver also features fl ywheel tuning, and
a
stereo indicator lamp to indicate when an FM
stereo signal is being received. The all-tran-
sistor construction provides long life, low heat,
freedom from hum and virtually service-free
operation. Excellent performance can be ex-
pected when this receiver is used with an an-
tenna ( either indoor or outdoor) that provides
proper signal pickup in your area. The re-
ceiver can be panel mounted or installed in one
of
the following Heathkit Accessory Cabinets:
Model AE-55 Walnut Cabinet; or the Model AE-
65
Metal Cabinet.
