S-76 receiver was manufactured from 1951 to 1954 as a lower priced running
mate to the popular SX-71. It sold new from $179.50 to $199.95.
It has a black satin steel cabinet with piano hinge top. In the first
year of production it did not have the plastichrome skirts that is found
on the later models and as seen on this receiver. The Band selector
range is: 538-1580 kc, 1.72 - 4.9 Mc, 4.6-13 Mc, and 12-32 Mc. The
bandspread dial is calibrated for 80, 40, 20, 11, and 10 meters.
||This receiver requires a speaker,
and Hallicrafters recommended the Hallicrafters R-46 speaker to
go with it. It has audio output of 500/3.2 ohms. Hallicrafters
was proud of its giant sized 4 inch S-meter. The S-meter adjustment
is on the rear.
||The Hallicrafters S-76 receiver
is a double conversion, superheterodyne communications receiver. It
has 9 tubes plus a regulator and rectifier. This receiver has
an antenna trimmer (see knob at the far top left of the front panel. The
antenna trimmer is attached to the main tuner capacitor. See the picture
of the inside), which is a popular add-on. It was discussed in a QST article
from the 1950s. It really does help to peak the antenna for various frequencies.
Another option is the crystal calibrator, (see top left of the picture of
the inside of the receiver). There is an on and off switch for this calibrator
on the front panel. It is also a nice additional feature.
||This Hallicrafters receiver
shipping weight is 46 pounds and is 18 1/2" wide, 8 7/8" high and 9 1/2"
Osterman, in his book Receivers Past and Present, lists this receiver as Scarce.
This receiver was truly a diamond in the rough when I found it. I almost didn't buy it, it looked so bad. In fact the only reason I got it was because it came with a R-46 speaker. The speaker looked bad but at least it looked like it had potential. However, with just a day's work this little jewel shined up, lit up and started to work really good. The receiver seems to be very sensitive on all bands. It picks up SSB very well for a receiver without a product detector, and the AM sound is great on the R-46 speaker.
