It had 3 "small" pins and one "large" pin. (Later UV based tubes relied on an index pin on the side of the tube base and UX tubes had 2 large and 2 small pins to ensure proper indexing.) It was replaced just a year later by higher performance tubes which were less likely to encounter the filament shorting problem, Westinghouse Electric's WD-12 ...
RCA 6DS4 "Nuvistor" triode vacuum tube, ca. 20 mm high and 11 mm in diameter Nuvistor with U.S. dime for scale. The nuvistor is a type of vacuum tube announced by RCA in 1959. . Nuvistors were made to compete with the then-new bipolar junction transistors, and were much smaller than conventional tubes of the day, almost approaching the compactness of early discrete transistor casi
EM34 tuning eye EM84 tuning indicator. A magic eye tube or tuning indicator, in technical literature called an electron-ray indicator tube, [1] is a vacuum tube which gives a visual indication of the amplitude of an electronic signal, such as an audio output, radio-frequency signal strength, or other functions.

The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
The 6SN7 has a 6.3 V 600 mA heater/filament. The 12-volt 300 mA filament equivalent is the 12SN7GT or 12SN7GTA. The 14N7 is the Loktal version of the 12SN7GT. There was also a comparatively rare 8V 8SN7 for 450 mA series-string TV sets) and 25 Volt/0.15 Amp heater version: 25SN7GT.
From 1931 RCA produced a range of small mantel radios called the Superette, which at introduction sold for $57.50 not including the vacuum tubes. [5] [6] "Super" was derived from superheterodyne. Probably the most well known is the Model R-7, which was produced in several versions. RCA also produced a console version, the model R-9.
The Victor Talking Machine Company was an American recording company and phonograph manufacturer, incorporated in 1901. Victor was an independent enterprise until 1929 when it was purchased by the Radio Corporation of America (RCA) and became the RCA Victor Division of the Radio Corporation of America until late 1968, when it was renamed RCA Records.
