    From a US Radio & Television brochure: The Gloritone 99A was manufactured by the United States Radio and Television Corporation of Marion, Indiana.

    The 99A is an ac-powered set that covers the standard broadcast band and uses 5 tubes: 224 (mixer/LO), 235 (IF), 224 (2nd detector), 247 (AF pentode), and 280 (rectifier). The mixer/LO uses a self-oscillating "autodyne" circuit. This was done to combine the operations of the mixer and oscillator into a single tube, thereby minimizing tube count and keeping production costs down. This was a fairly common practice in economy sets of the era. The radio has no Automatic-Volume-Control (AVC) and has its manual volume control placed within the antenna circuit. This same chassis was used for both the 99A table model and the 99B floor model radios.
