1, Teghnioal data in typed form for the SRS 551 (=RS 1003) and EL 153 tubes have recently
l
become available in the tube department of VEB Werk fuer Fernmeldewesen WF.
In the first quarter of 1955, the total production of all tubes of the LD series
was, about 100 per month. All were delivered to VEB Saohsenwerk Radeberg..
3. A small number of specimen travelling-wave tubes has been delivered to VEB
Saohsenwerk Radeberg for trials, but none has yet been used in equipment produced
by that factory. Output measurements of travelling-wave tubes and klystrons

Russia. No noise measurements have yet been made, because no calibrated noise
source is available. It is expected that a conference will take place shortly
between representatives of VEB Work fuer Fernmeldewesen WF and VEB Sachsenwerk
Radeberg to discuss the uses to which travelling-wave tubes will henceforth be put.
Dr. Franz Heinrich Lange, ohief of development at VEB Funkwerk Leipzig-Plagwitz is
showing great interest in the push- up tetrode SRS 4451, presumably for use in the
construction of small transmitters.
5. The double-chamber klystron 2 A 10 is still in the course of development at VEB,
Funkwerk Erfurt.
A conference on the production of subminiature tubes is expected to take place
during May 1955
Comment. Production of this tube was reportedly; begun in the beginning
f 1955.
