Network tube radio receiver `` Aquamarine ''.
Tube radios.DomesticThe network tube radio receiver "Aquamarine" was developed in 1955 by the Riga State Electrotechnical Plant VEF. By 1956, the design bureau of the VEF plant had developed a number of high-end radio models, which significantly influenced the development of the Soviet radio industry. Many of the promising new radios were shown at various exhibitions, but were never delivered to the conveyor. The receivers had a modern design, a wide range of functions (automatic tuning, tone registers, remote control, VHF range) and high acoustic characteristics. Experienced receiver "Aquamarine" has 7 ranges: DV, SV, KV1..KV4, VHF. The bottom row of keys is a tone register that discretely controls the frequency response of the bass amplifier and a motor automatic tuning unit with complex mechanics.
