Network tube radio receiver TsRL-10 and TsRL-10K.
Tube radios.DomesticSince 1935 and 1936, the network tube radio receiver "TsRL-10" and "TsRL-10K" has been produced by the Leningrad plant named after Kozitsky. Since the fall of 1935, the first mass serial domestic superheterodyne TsRL-10 (10th development of the Central Radio Laboratory) was produced. The radio receiver circuit is made on 5 radio tubes with 4-volt heating types; SO-183, SO-182, SO-193, SO-187, in the VO-116 rectifier. The radio receiver "TsRL-10" network, 110, 127, 220 V, operates in the ranges: DV 740 ... 1900 m, and SV 220 ... 550 m. The sensitivity of the radio receiver is 150 ... 500 μV. Selectivity on the adjacent channel 24 dB, on the mirror channels 8 ... 12 dB. The IF is 110 kHz. The rated output power of the radio receiver is 1 W. Power consumption from the network is 100 watts. There are jacks for connecting an external pickup. The volume control and treble tone are smooth. Vernier device with 10: 1 deceleration. It is known about two minor circuit upgrades of the TsRL-10 receiver. Since 1936, the plant has been producing a modernized receiver "TsRL-10K" (Shortwave), similar in design, appearance and electrical circuit to the "TsRL-10" model), having a range in DV, SV but with the addition of HF range of 19 ... 46 meters. unfortunately the release of both receivers did not become mass due to the lack of modern radioelements and the unavailability of adjacent enterprises to establish their production.More about the models in the documentation below.
