All representatives of the "popular" radio, including Moskvich and all models of ARZ, had only two frequency ranges - "Middle Waves" (Brodcasting) 200-550 meters and "Long Waves" - 800-2000 meters. And only all models of radio receivers Record and Dnepr 52, which were a little higher class, had an additional range of "Short Waves" 25m-75 meters.
The output stage of the amplifier in all models of the radio of this class was made on a 6П6С lamp - which has an American analogue of 6V6GT. In the universal Records 47 with a universal power supply, as well as in ARZ-49 the amplifier was built on a 25П1C or 30П1C (25L6-GT) radio lamp. The frequency converter was based on a 6A7 (6SA7) lamp, while the reflex cascade in Moskvich radio and all ARZ models was made on a 6B8 lamp. In all other 5-tube models, the radio frequency cascade of the HF was made on a 6K3 lamp, and before the LF on the 6Г2 lamp (6SQ7).
