The Magnavox 342K console is a two-chassis radio-phono using a tuner (CR-202C) that covers the AM broadcast band, the short waves from 5.5 to 17 MHz, and the post-war FM band (88-108 MHz). It also features separate Bass and Treble controls, a wide "hi-fi" IF bandwidth for AM/SW complete with a 10KHz inter-station whistle filter, and a "sharp" selectivity position on the treble switch that can reduce wide IF AM bandwidth on a crowded BC or shortwave band. It has one RF amp stage, two IF stages for AM/SW and a limiter/ discriminator circuit for FM detection. It also has a switch-selected "external" line input that will enable connecting a modern line-level audio source. The separate audio power amp (AMP-109) features four 6V6GT tubes in push-pull parallel. Details of the tube complement of the tuner and amplifier and further specifications can be found under their respective listings. It is a 1947 model (typically introduced in the prior year).
