receiver was manufactured by Hallicrafters from 1949 to 1954. They
made the receiver with white and black dials. The white dials were
for the earlier models (approximately 1949-1950) and the black dials came
out in the later years of production. The SX-71 has a black satin
steel cabinet with chrome trim, and a piano hinge top. This receiver
is not light...it weighs 33 pounds and is 18 1/2 inches wide, 7 7/8 inches
high and 12 inches deep. Its sale price ranged from $179.50 to $249.50.
This was my 3rd receiver when I was a kid, and it was quite a step
up from my Hallicrafters 38-C receiver. It really is a nice general
coverage receiver that includes ham band bandspreads.
The Hallicrafters SX-71 receiver is a double conversion superheterodyne general coverage communications receiver with 14 tubes. The frequency coverage is from 538 kc to 35,000 kc and 46 - 56 MHz. It not only picks up AM and CW signals, but it receives narrow band FM. It has good selectivity and sensitivity and has 3 watts of audio output. It sounds good with a Hallicrafters R-44B speaker (manufactured for the receiver with white dials) or R-46 speaker (manufactured for the receiver with black dials).
