Stewart-Warner "Ferrodyne" Chassis Model R-136 7 Metal Tube All-Wave Superhet.

The model 13.62 set (illustrated), which has the type R-136 chassis, has a new-style cabinet. Three wave bands are available. The set is designed to get the most out of the new metal tubes, and the so-called Ferrodyne chassis is used, this chassis having been designed only for use with the metal tubes. It is used in several receiver models (Nos. 1361 to 1369), which include all cabinet types.

The use of a doublet-type antenna with this set is highly recommended. This may consist of a 41 ft. length of wire split in the center by an insulator, and provided with two twisted wires as a lead-in. No special kit is required. An ordinary antenna will, however, give very satisfactory results, espe­cially on the broadcast band. The dual line filter is designed to remove any noise that may come in over the power line and is very efficient for this purpose. The 2-speed station selector is ball-bearing, gear driven, and provides accurate control of station selection. Automatic station register permits the operator to instantly tune in the station desired to perfect resonance. Metal tubes must be used in this set, as it was not designed for glass tubes.

There are 202 Radio Service Data Sheets as of July 21, 2017.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
