Early Electronic Television
TK-1
The following is a rough translation of information from the Moscow
Polytechnic Institute:
This set was made at the Kozitskogo Radio Plant in Leningrad in
1938. It was designed for reception of 343 line broadcasts from the
Moscow television center. The engineers at Kozitskogo used many of
the features of the American RCA RR-359 set, which was made in 1934.
This was a complex and expensive model using 33 tubes and circular
kinescope about one meter long. Many parts were supplied by RCA. Six
thousand TK-1s were made. |
This is from a Russian
website (rough
translation):
In 1938 the TK-1, based on an American set manufactured by RCA was made. This
electronic television receiver has a rather bulky cabinet, in which the
picture tube is positioned vertically, while the audience did not look at the
screen, mounted horizontally, but at its reflection in the mirror, fastened on
the inside of the hinged lid. The CRT had a diameter of 23 cm. Such a design was
determined by the size of the tube, which was about a meter long. Televisions
were installed in "Workers' Clubs", the "Red Corner", the Polytechnical Museum
and other public facilities.
The TK-1 was made in a radio plant in Leningrad plant, called Kozitskogo, 6000
sets were made.

RCA provided about 75 of its RR-359 receivers to the USSR in the late 30s, along with broadcast
equipment. The TK-1 shown above looks similar, but is shorter. The speaker area
is about half the height of the RR-359. Since the CRT in the RR-359 extends to
the bottom of the cabinet, it is unclear how the TK-1 would work, unless it used
a different CRT. Below is another TK-1 with a taller cabinet.
