Black and white televisionsDomesticTV "Foton-225 / D" presumably since 1982 produced the Simferopol TV Plant named after the 50th anniversary of the USSR. The unified semiconductor-integrated TV of the second class "Foton-225" (UPIT-61-II) with the use of integrated microcircuits was produced in 2 versions: a model with a decimeter block "Foton-225D" and a model without a decimeter block "Foton-225". The TV uses a 61LKZB-K kinescope with a diagonal screen size of 61 cm and a beam deflection angle of 110 degrees. The TV provides reception on any of the 12 channels of the MB range, and the TV with the "D" index, in addition, on any of the 21 channels of the UHF range. The model uses: AGC; APCHG; AFC and F line scan; protection of the picture tube from burn-through when turned on; limiting the beam current of the picture tube; electronic voltage stabilizers that ensure the stability of the electrical parameters of the TV. Possibilities for connecting a remote control for brightness and volume are provided; a tape recorder for recording sound; listening to sound on headphones when the loudspeakers are off. Sensitivity in the MV range of 55 µV, in the UHF 150 µV. Resolution 500 lines. The band of reproducible sound frequencies is 100 ... 10000 Hz. Rated output power - 2.5 W. Power is supplied from a network with a voltage of 110, 127, 220 or 237 V. Power consumption is 90 W. The dimensions of the TV are 690x490x410 mm.
