Portable transistor radio "Sverdlovsk".

Portable radio receivers and radios on p / p.DomesticSince 1957, the Sverdlovsk portable transistor radio has been produced by the Kamensk-Uralsky Instrument-Making Plant. The Sverdlovsk radio receiver is a portable, battery-powered, dual-band superheterodyne built on transistors. Ranges of received frequencies DV and MW. Radio stations are received via an internal magnetic ferrite antenna. The radio receiver uses seven transistors and one diode: P6G frequency converter, P6G local oscillator, P6V (2 pcs.) Intermediate frequency amplifier, DG-Ts8 - detector, P6V - low frequency preamplifier, P6V (2 pcs.) - push-pull final low power amplifier frequency. The radio is powered by three KBS-L-0.5 batteries from a flashlight. The supply voltage is about 12 V, the current consumption is 23 mA at rest. The radio uses an electrodynamic loudspeaker 1GD-9. The nominal output power of the receiver amplifier is 100 mW, the maximum is 200 mW. The dimensions of the radio receiver are 250x170x85 mm. Its weight with batteries is 2 kg. In total, about 100 copies were released.
