1. Production of tubes at the RFT Erfurt in November 1953 was at the same rate as
previously. A larger production volume, however, is planned for 1954. The
increase will not be attained by new investments, but various tube types will
be taken out of production, including the so-called "rted series," which until
recently have still been manufactured for the Soviet Union. They belong to
the 9 series of tubes. The production of E tubes of the 11 series uiil also
be reduced. The D tubes will be taken out of production altogether.
2. It is planned to have the production of the 181 series going in greater volume
by early February. This series until now has been under developpment,
but the work has been finished. The tubes are characterized by a sral.ier size
(about 3 cm) and better capacitive qualities between gr1O rA P-ode. Pro'--in
of so-called high frequency tubes will also commence in early February.
These tubes provide the frequency rectification and mixing .Lit n gn s requer..:,
amplification. Power tubes will not be produced for the time being.
3. The stFT broadcasting plants have been directed to adjust their broadcasting
equipment for the future to the heretofore conventional tubes. The ECH 181
tube will not be available to civilians in future; it is manufactured by
three works in the Zone: RFT Erfurt, ichrenwerk Neuhaus, and HF Berlin. A
smaller plant in Leipzig, likewise belonging to the RFT, will still participate
in the production.of the EF 181 tube.
4. The E 181 series in future will mean 6.3 volt and 200 milli-amphere tubes. In
designating tubes, C signifies triode; H, hexode; F, pentode for high
frequency amplification; B, duo-diode for high frequency rectification;
L, end pentode or tetrode.

The production of quartz crystals is also to be increased. kppropriate
directives have already gone to the Sazon quartz smelting and working plants.
These crystals are especially in demand by the Soviet Union.' They are valued
First of all for special high frequencies, on account of their small weight
and minimum size. The crystals are held between two silver plates which
are pressed against the crystal-by springs. These crystals have no longer
been produced in the usual quantities of late because the silver now delivered
is-as good as none. How high the production is to be is not decided.
The R1'T Erfurt delivered 16 oscillographs to.the Soviet Union in November 1953.
They were for Soviet factories. Seven electronic voltmeters for the Soviet
Union were also delivered to the Bureau of Weights and Measures to be
adjusted. Two 20 watt telemeters. were delivered to Czechoslovakia; another
of the same capacity will be delivered to the Soviet Union on 15 Jan 54.
Material shortages are chiefly anode plates and wire for base feeder lines
(Durchleitung). There are also difficulties with the supply of fluorescent
material. The Thuringian plants cannot furnish enough material to the DHZ on
account of their deliveries to the Soviet Union.
