This displays incoming signals for precise tuning, strength
of signal, correct antenna orientation and station bandwidth
modulation. It may also be used for observing the degree of
stereo separation, stereo phasing of all stations and other
components connected through the Model 18 Receiver.
PASSIVE FRONT END
Inspired by the techniques used in radar reception, this
revolutionary tuning section design eliminates “RF overload”
from strong stations and lets weak signals come in without
being swamped out by strong ones. It also gives a better
signal-to-noise ratio and lower distortion. It is called
“passive” because there are no tubes, transistors, FET's or
IC’s in the front end to interfere with the purity of the
Incorporated in the IF stages, these assure better
selectivity, lower distortion, and more than 30 db stereo
separation, even at 15 KHz. 1 Because of them, the IF stages
never require realignment.
Selecting stations becomes a delightful experience with this
unique control in which you rotate the actual tuning bar
flywheel. This results in silky-smooth, ultra-low friction
DIRECT COUPLE DESIGN AND PROTECTION CIRCUITS
Through these, the amplifiers recover instantaneously from
overload. They also protect both amplifiers and loudspeakers
against sustained overload damage caused by short circuits
or other accidental misuse.
FRONT PANEL TAPE RECORDER DUBBING CONNECTIONS
These provide convenient facilities for making tape copies
with an external recorder.
FRONT PANEL STEREO HEADSET OUTPUT
You can listen to stereo headsets with or without the
Because the tuning dial is three inches longer than on most
receivers, you can more accurately "zero in” on the optimum
signal strength of a given station.
1% RESISTORS USED
The best resistors available, they give supremely low
distortion. They are used throughout the receiver in all
MASSIVE HEAT SINKS
These dissipate heat from the power transistor circuits, and
that means longer years of use.
