Description

Direct heated 3,3-V-Triode for dry batteries: UX199 = CX299 = X99.

The "Saga of the vacuum tube" by Tyne tells us on page 314: "In April 1925 the UV199 was superseded by the UX199, announced August 1, 1925. Production continued up to 1931, although after 1927 few new receivers were built to use it. Nickel-plated contact pins were introduced in 1927."

After some time the UX tubes were noted only by the numbers and a bit later only by the last two digits.

In 1930, with the introduction of the 230 and 231 tubes with a "T9" (1 & 1/4 inch diameter) bulb size, the older "T8" (1 inch diameter) size was discontinued and the UX199 was available for a short while with the bigger size bulb. The old shouldered base was also changed to one of the same diameter as the new bulb. At least Philco also made the larger 99 type tubes.

Following the commercial availablility of the RCA UX199 oin August 1st, 1925, many manufacturers made the tube, some with their own letter prefix. It was also available as the X99, 99X, 99 and 199. The first and principle manuafcturer for RCA was the one of the mother companies of RCA, General Electric (GE) USA. The RCA UX199 was discontinued in 1931.
