• Model: 69 All Wave-Selector - Stromberg-Carlson Co. ;

• Shape
• Tablemodel, Tombstone = decorative upright, not cathedral but can have rounded edges.

• Notes
• The Stromberg-Carlson No. 69 All-Wave Selector is a Superheterodyne Frequency Changer. Has to be connected to the RF input (Ant. and GND connections) of a good standard broadcast receiver which needs to be tuned to 545 kc (IF) to receive the SW bands. BC is still tuned as usual. The Converter gives an extension of the tuning range from 1500 kc to 25 Mc. There seems to be a model 69 without own power supply, all necessary voltages being provided by model 68 power supply. See model 68.
