• The Stromberg-Carlson model 55 is an 8 tube, AC operated BC band receiver with push-pull output stage and consists of two units. The remote selector unit contains the RF amplifier(78) and oscillator/mixer(6A7) tubes. The speaker amplifier unit contains the IF amplifier(58), demodulator(55), AVC(2B7), audio amplifier(Qty 2 - 2A5), power supply(80) tubes and speaker. The two units are connected with a multi-conductor flat cable. The model was available with either a 50-60Hz power supply or a 25-60Hz power supply, but there is no difference in model name.
