Black and white televisionsDomesticThe unified TV set "Kaskad-230 / D" (UST-61-7 / 8) has been produced since 1985 by the Kuibyshev software "Screen". The TV is made on a block-modular principle, using microcircuits. Programs are received in the MV range with the SKM-15S channel selector, as well as in the UHF range when installed or with the SKD-22S selector already installed (index "D"). The TV uses a 61LK3B explosion-proof kinescope, with an electron beam deflection angle of 110 °. The TV has: automatic gain control (AGC); automatic adjustment of the frequency of the local oscillator APCG; automatic adjustment of the frequency and phase of the master oscillator of the horizontal scan AFC and F; protection of the kinescope from burn-through when the TV is turned on; limiting the beam current in the CRT; electronic stabilizer of the supply voltage from the network. The TV provides: connection of a wired remote control for brightness, volume and speaker off; connecting a tape recorder for recording; listening to the soundtrack of television programs through headphones. The TV set is assembled from functionally complete unified blocks and modules. In total, 217.5 thousand Kaskad-230 / D TV sets left the factory assembly line.
