TV "Zorka" (analogous to the TV "Lotos" of the Simferopol TV Plant) has a number of significant advantages over the previous model.
,86e6f450b8cc469628ba70bf2947b049
"Zorka" is a desktop TV (CNT-47) with a tube screen size of 47 cm diagonally.
,86e6f450b8cc469628ba70bf2947b049
The new model uses a new explosion-proof kinescope 47LK-2B with a beam deflection angle of 110 degrees.
,86e6f450b8cc469628ba70bf2947b049
The image on its screen is bright and contrasting.
,86e6f450b8cc469628ba70bf2947b049
The TV "Zorka" uses APCG, a number of other automatic settings and innovations.
,86e6f450b8cc469628ba70bf2947b049
At the beginning of 1967, the plant improved the TV and began producing it with the name Zorka-1 (UNT-47-1).
,86e6f450b8cc469628ba70bf2947b049
In the spring of 1969 the plant mastered the production of the Zorka-2 TV (ULPPT-47-1).

The advantages of the Zorka-2 TV set over its predecessors are obvious.
,86e6f450b8cc469628ba70bf2947b049
The model uses transistors.
,86e6f450b8cc469628ba70bf2947b049
Instead of lamps, GT313 transistors are installed in the UHF.
,86e6f450b8cc469628ba70bf2947b049
The LF preamplifier uses an MP40 transistor.
,86e6f450b8cc469628ba70bf2947b049
In the frame scanning unit, a thyratron lamp with a cold cathode is used.
,86e6f450b8cc469628ba70bf2947b049
Frame rate adjustment is now automatic.
,86e6f450b8cc469628ba70bf2947b049
The reliability of the TV has increased, power consumption has decreased, and the acoustic reproduction of sound has improved.

In the spring of 1970, the plant is preparing to release a new model, a TV with the name "Zorka-3" on a large picture tube of type 59LK-1B, but everything was limited to the release of only an experimental batch and the TV "Zorka-2-1" went into series, however, it did not differ from the model
,86e6f450b8cc469628ba70bf2947b049
"Dawn-2".
,86e6f450b8cc469628ba70bf2947b049
The plant began producing a large-screen TV, almost a complete analogue of the Zorka-3 model, since the end of 1970 under the name Zorka-201.
