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 ...
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.
Dimensia (/ d ɪ ˈ m ɛ n s i ə / dih-MEN-see-uh) was RCA's brand name for their high-end models of television systems and their components (tuner, VCR, CD player, etc.) produced from 1984 to 1989, with variations continuing into the early 1990s, superseded by the ProScan model line.

The BC-348 is the 28 vdc powered version of the 14 vdc powered BC-224. The first version, the BC-224-A, was produced in 1936. [1] Installed in almost all USAAF multi-engined transports and bombers used during the fifteen-year period from before World War II through the Korean War, BC-348 radio receivers were easy to operate and reliable.
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.
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
