  • Notes

  • Raytheon used its chassis 4D16-A for three Alarm-Clock Radio models with the same cabinet in different colors: Model C-50B is in Walnut, Model C-51W is in White and Model C-52R is in Red. According to Beitman volume R-16 from 1956 they can have either a 12AT6 or 12AV6 as 2nd detector, AVC and first audio. Built in loop antenna attached to the cabinet back. Has a single Selenium Rectifier.

    According to SAMS Photofact 212-5 from August 1953 the chassis 4D16-A was first used for the models CR41, CR41-A (both Mahogany), CR42, CR42-A (both Ivory), CR43, CR43-A (both in Red) and Western Auto models Truetone D2216A and D2217A. The manual of 1952 "most-often-needed radio diagrams" shows under Montgomery Ward also the Airline Clock Radios models 15BR-1548A, 15BR-1549A, 25BR-1548B and 25BR-1549B for this chassis, which are documented in Photofact 191-3 from January 1953.
