* RMA/JEDEC register record available by courtesy of TCA* - This tube was already listed by several manufacturers when RMA started its standardization in 1934. In order to characterize popular receiving types, manufacturers were asked to supply average characteristics as measured on production lots. Here are the filled answer forms supplied by Radio Valve Co., Raytheon, Sparton, Triad, Tung Sol, Ken Rad, Hytron and Arcturus. Full record is downloadable here.

The type 84 tube was originally developed by Sylvania and first marketed by Philco in 1933. It was made with the S12 size bulb, by manufacturers such as Arcturus (with blue glass), Ken-Rad, National Union, Philco, and Sylvania. It was sold originally in March 1933.The companies listed above made the tube with the ST12 bulb and tubes of later manufacture had the double brand 84-6Z4.
