The television receiver of the black-and-white image "Record-8" since October 1966 has been experimentally produced by the Aleksandrovsky Radio Plant.

The development of a fundamentally new mass 12-channel TV set "Record-8" (LPPT-40) began in 1965.
,86e6f450b8cc469628ba70bf2947b049
Specially for this model, a rectangular picture tube of the 40LK3B type with a neck length of 345 mm was developed and put into industrial production.
,86e6f450b8cc469628ba70bf2947b049
The kinescope had sufficiently high lighting parameters, a white glow and a resolution of 600 lines in the center.

"Record-8" TV set is assembled on lamps and semiconductor devices.

Transistors are used in UPCHI, UPCHZ blocks and in the LF preamplifier.
,86e6f450b8cc469628ba70bf2947b049
The sensitivity of the TV is 200 μV.
,86e6f450b8cc469628ba70bf2947b049
The nominal output power of the audio channel is 0.5 W.
,86e6f450b8cc469628ba70bf2947b049
The range of reproducible sound frequencies is 100 ... 10000 Hz.

By the fall of 1966, the documentation for the ULPT-40 TV was transferred to several radio plants of the country for the preparation of their industrial production, in particular to the Kuntsevsky Mechanical Plant, where the Yunost-40 TV (ULPT-40) was developed and prepared for production in the shortest possible time
,86e6f450b8cc469628ba70bf2947b049
and to the Novgorod Television Plant, where the TV "Volkhov-3" (ULPT-40) was prepared for production.
,86e6f450b8cc469628ba70bf2947b049
Both TVs differed from the basic only in their external design.
,86e6f450b8cc469628ba70bf2947b049
Prototypes were manufactured at both factories.
,86e6f450b8cc469628ba70bf2947b049
The TV "Record-8", which has already gone on sale at a price of 180 rubles, which was cheaper than the TV UNT-35, almost immediately fell on a stream of complaints about the high noise level of the image at a distance of 30 ... 50 kilometers from the TV center, while
,86e6f450b8cc469628ba70bf2947b049
UNT-35 TVs worked without these problems at a distance of up to 90 kilometers.
,86e6f450b8cc469628ba70bf2947b049
The reason for the noise was in the intrinsic noise of the transistors, which almost did not appear with a powerful signal from the TV studio.
,86e6f450b8cc469628ba70bf2947b049
Due to the low price, TVs were mainly bought by residents of rural areas, where they could compare the work of the new model with TVs UNT-35.
,86e6f450b8cc469628ba70bf2947b049
After checking the complaints, the TV "Record-8" was discontinued, and the TV sets "Yunost-40" and "Volkhov-3" were not put on the conveyor.
