Since October 1963 and January 1964, the Petropavlovsk Plant named after SMKirov has produced radio receivers network lamp "Kazakhstan" and "Kazakhstan-2". The Kazakhstan broadcast receiver was developed in 1962 to replace the outdated TPS-54 model. The receiver was successful in a schematic and constructive relationship and stayed on the conveyor until mid-1975. In total, over the years of production, 150 thousand copies were produced, and the mass production fell on the period 1970 ... 1974. During production, the receiver has undergone several circuit and technological upgrades. The Kazakhstan-2 receiver has undergone modernization and was distinguished by the presence of a second local oscillator for receiving telegraph and single-band signals, while simultaneously upgrading the baseline in which only 10 lamps were left after the alteration. '' Kazakhstan '' receiver of the highest class. It uses 14/12/10 finger lamps, a 4-section tuning capacitor, an electron-beam tuning indicator. The receiver could be used as a broadcast, consumer, control, for amateur radio communications, etc. The design of the receiver is designed to work over a long period of time. The radio receiver has 7 bands, these are LW, MW, and 4 HF subbands, in which continuous overlapping in frequencies from 3 to 18 MHz and the VHF-FM range is performed. The switch ranges drum, with a soft connection of contacts. The radio receiver is assembled on finger-type lamps, among which there is an anodic voltage zener diode and a breeder of stabilization of the local oscillators. In the FM band there is an AFC, while receiving AM signals, a deep AGC and an IF bandwidth adjustment are provided, from 5 to 18 kHz. The receiver can work with several types of antennas and with two antennas at the same time, providing, in conjunction with the AGC, practically free reception in the HF bands. Not all upgrades were successful, so after replacing the 6H2P detector with semiconductor diodes, the dynamic range of the AGC narrowed, and in the modernization, where the detectors and the AGC are combined in a 6H2P lamp, the AGC deteriorated.After replacing the 6N14P amplifier lamp on a 6P14P and single-ended push-pull output transformer, although the sound became more powerful, there were no significant distortions before.
