Souvenir '' Lamp with receiver ''.
Radiols and receivers p / p stationary.DomesticThe souvenir "A lamp with a radio receiver" has been produced since 1975 in Zaporozhye (PO Box 745). The souvenir is designed for reception in the range of medium waves and illumination of a small space, it can be used as a "night light". The radio receiver is assembled according to the direct amplification scheme 3-V-3 on seven germanium transistors according to the transformerless scheme. Sensitivity with a magnetic antenna - 3 ... 5 mV / m, selectivity - 6 ... 8 dB. The rated output power is about 80 mW. The range of reproducible frequencies is not more than 250 ... 3550 Hz. The receiver and the flashlight lamp are powered from the mains power supply. The light bulb and the radio are separately switched on and off. In the mid-80s, the receiver circuit was converted to silicon transistors. Accordingly, the printed circuit board changed, and later the power supply was also changed. The technical parameters remain the same. The color of the glass of the lamp could be red.
