TV b / w images "Rubin-110" and "Rubin-111" since 1967 produced the Moscow Television Factory. TV "Ruby-110" in its technical parameters belongs to class 1. The scheme was developed by the special design bureau of the plant together with the Scientific Research Institute of the Moscow PIU of the USSR, taking into account the latest achievements of TV equipment. The TV has a 65LK1B kinescope with a screen size of 65 cm diagonal and a beam deflection angle of 110 ° and an improved speaker with two 4GD7 loudspeakers, a number of new radio tubes. Switching channels and touch is a button click. In addition to the usual selector, there is a converter that allows you to receive telecentres operating in the UHF. The sensitivity of the model in the MV range of 20 µV. 50 dB selectivity. The clarity in the center of 500 lines. Brightness and contrast increased due to an increase in accelerating voltage of the kinescope. The TV has a clearness corrector. Improved sound quality. The band of reproducible sound frequencies increased to 50 ... 12000 Hz against 100 ... 10000 Hz in models of the 2nd class, the nonlinear distortion coefficient was reduced to 4%, and the sound pressure was increased to 1 n / m. The sound quality of the TV is not inferior to the best samples of the 1st class receivers. Improved APCG. The presence of the corresponding device allows the sweep generators to automatically enter synchronization, therefore, there are no line and frame frequency control units. Improvements made to the setting and remote control. The choice of a television center on any of the 12 channels is made by pressing one of the five keys on the front panel. The transition to receive in the UHF is performed by pressing the sixth key.

To indicate the channels on the front panel of the TV set a digital pointer. In addition to switching programs from the remote control, you can adjust the brightness, volume, turn on and off the TV. Headphones can be connected not only to the TV but also to the remote control. Developed several options for the design of the TV; for installation on the floor, table and for embedding in sectional furniture, in this case, the TV is divided into two parts, in one is the speaker and input devices, and in the other everything else.A cheaper version was also produced, the TV "Ruby-111", which is distinguished by the absence of keyboard and remote program switching, and the channel was determined by the position of the PTC handle. Televisions were produced until the end of 1970, and a total of 2,909 copies were produced. Model constructors: Ya.F. Ephrussi, L.E. Kevesh, V.P. Goranskaya, A.F. Krasilnikov.
