Local-Distance Switch. Sensitivity is 1.25 microvolts per meter. "Stadium Speaker and push-pull output. There is an early (Rider's 6-2 to 6-4) and a late version (Rider's 6-5) of the chassis/schematic with only minor differences - we distinguish this only with the chassis model, but there are also two different resonance meters. The concept is a dual speaker (in one), one designed to give best response on the higher audio frequencies and the other designed to give best response on the lower frequencies.

    This model is sold as chassis including loudspeaker for $ 49.50, for $ 58.95 including RCA licensed tubes and Aerial Equipment or for $ 60.60 ($ 115.00) if RCA tubes are delivered. With additional $ 3.00 it can be operated with 220 Volt AC.

    As console receiver the 10 Tube Duo-Symphonic is named C10, 101 (as lower console) and 102 or 1102 (RCA tubes), as phonograph combination it is the 225P (page 17). Pages 20 through 23 show it and the 10 tube chassis for "De Luxe" cabinets no. 162, 181, 179 and 184. See details or summaries about this catalog.
