25-159 Hallicrafters S40A Receiver
The S-40 Hallicrafters line began in 1946 and lasted until 1954. With eight tubes, Model S-40 was the mid-level Hallicrafters receiver of the late 1940s and early 1950s. The S-40B was made from 1950-1954 and sold for $129.95.
The entry-level receiver during those years was the six-tube S-38, one of the best-selling shortwave sets of all time, retailing for about $40 to $50. If you wanted a top-of-the line Hallicrafters in 1946, you went for the fifteen-tube SX-42, which retailed for $275, roughly double the price of an S-40 and almost six times the price of the original S-38.
The tubes are: 5Y3GT (rectifier), 6SQ7 (RF amplifier), 6SA7 (osc. mixer), 6SK7 (1st IF amplifier), 6SK7 (2nd IF amplifier), 6H6 (detector/automatic noise limiter), 6SG7 (BFO/1st audio amplifier), and 6K6GT (audio power amplifier).
