Development of the low noise-level trave:11irig- ave tube is not complete; its

completion is expected during 1955 and the pilot series will be built during 1957.

5. A small run of transistors is to be built to replace the production of VEB
Werk fuer Bauelemente der Nachrichtent chnik "Carl von Ossietzky", Teltow, which
has been cancelled.
6. At the beginning of the year the tube development department was reorganized
into the following sections: broadcast tubes; ga.s-filled tubes; transmitter
tubes; cathode ray tubes; transistors.
7. Early in December 1954 a new regulation was issued under which a pilot series
cannot be produced in the plant until the permission of the Ministry of Machine
Construction has been obtained. This will only be given when the corresponding
number of orders has been received., this effectively preventing the demonstration
of a new development by a pilot series.
1. Comment. VEB Funkwerk Koepenick has been enquiring about the supply
of magnetrons for radar purposes.
C e . these are being developed on the plant's own initiative, i.e.,25X1
without any order having been placed. We do not know what they are.
