The radio receiver and the radio tube network tube `` Mir M-154 '' and `` Mir M-154R ''.

Tube radios.DomesticSince the beginning of 1955, the radio receiver and the radio tube network tube "Mir M-154" and "Mir M-154R" have been produced at the Riga State Electrotechnical Plant VEF. The 1st class receiver "Mir M-154" is an upgrade of the Mir M-152 model and, in addition to the improved appearance and electroacoustic data, it coincides in technical parameters with it. On its basis, the Mir M-154R radio was created, which is distinguished by the use of a universal EPU. The appearance of the models has not changed much, except for the transfer of the lamp for the tuning indicator from the center to the left side of the front panel, replacement of radio fabric, The dimensions of the case have been reduced, the loudspeakers have been replaced, the number of lamps has been reduced to 11, the 6P3S lamps in the LF amplifier have been replaced by 6P6S, the local reception mode has been introduced, the number of HF sub-bands has been reduced to 3. There are two loudspeakers: 4GD-3VEF and 4GD-4VEF , they are the same in frequency response, but differ in resonance frequencies.The EPU has 2 speeds of rotation of the disk 78, 33 rpm and consists of a DAG-1 engine with a hitchhiker and a piezoelectric pickup ZPK-54. The dimensions of the receiver and radio are ideal. The weight of the receiver is 35 kg, radios 42 kg Power consumption by the receiver is not more than 100 W, by the radio while playing records 120 W.
