RCA Victor M-105


RCA Victor, M-105, 4-tube superheterodyne. Employs a mechanical inverter and rectifier for the "B" power supply, thus eliminating a tube.

A receiver which features mechanical simplicity in construction and design. Only the following 4 tubes are used: one (each) type 78 (R.F. amplifier), 6A7 (first-detector and oscillator), 6B7 (I.F. and second-detector), and 41 (power output). A combined mechanical vibrator and mechanical rectifier inverter eliminates the necessity of a rectifier tube. The circuit employed is superheterodyne design.
