- Bemerkung
-
The original tube line up has to be UV199 if this model has arrived in 1923:
The "Saga of the vacuum tube" by Tyne tells us on page 314: "In April 1925 the UV199 was superseded by the UX199, announced August 1, 1925.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. The UV199 was introduced in December 1922, the same time as the UV201A.
