R-42 Speaker
The Hallicrafters R-42 and the R-45 (the rack mounting version of the R-42) speakers were manufactured beginning in 1947 to match the new Hallicrafters SX-42. It was touted to be one of the greatest innovations in speaker design. This was the first speaker of its size to offer the bass reflex principle. The cabinet size is 12 1/2 inches deep, 11 3/4 inches high and 17 inches wide. The speaker size is 8 inches. A two position switch on the front panel offers communications or high fidelity reception. The terminals on the rear are for 500/600 ohm line. The R-42 speaker was manufactured from 1947 to 1948 and sold for $25.00. The R-45 speaker sold for $27.50. The R-42 is my favorite speaker...I have four of them!
The Hallicrafters SX-42 AM/CW/FM receiver was manufactured from 1947 to 1950, and was one of the first receivers designed after World War II. The receiver covers from 540 kilocycles to 110 megacycles. This "tremendous frequency coverage" is made possible by the development of a new "split-stator" tuning system and the use of dual intermediate frequency transformers. The receiver has a high fidelity phonograph amplifier with a response curve essentially flat from 60 to 15,000 cycles and an undistorted output of 8 watts. Musical reproduction is wonderful, especially on the Hallicrafters R-42 speaker. This is my favorite receiver and it was made the same year I was born!
The Hallicrafters SX-42 is a single conversion superheterodyne receiver with 15 tubes. The circuit for this model changed several times over its production life. Bands cover 80, 40, 20, 10 and 6 meters. This unit is 20 inches wide, 10 1/4 inches high and 18 inches deep. It weighs 52 pounds. It sold from $250 to $275 new. |
