| Description |
History (Tyne 324): In 1925 two small full-wave rectifiers came on the market, the Westinghouse UV196, and the GE UX213. The UX213 was the first full-wave rectifier offered for sale by RCA. Work on this tube was started late in 1923. In December 1923 the designation Rectron UV213 was assigned. The final design was arrived at in the summer 1924 and was announced as UX213 in September 1925. It was superseded in May 1927 by the UX280.
Cunninghams designation was CX313, but the tube was certainly produced like all the Cunningham tubes by RCA
