The 75A ham band receiver presented in 1946 with it's crystal controlled first oscillator and permeability tuned second oscillator was considered as an all-time classic amateur receiver.

The smaller "S-Line" ham band (75S) and general coverage (51S) receivers, transceivers and linear amplifiers followed at the end of the fifties.
