Stationary transistor radio receiver `` SN-25 / P ''.
Radiols and receivers p / p stationary.DomesticStationary transistor radio "СН-25" and "СН-25П" have been produced since 1978 and since 1988 by the Novosibirsk Electrovacuum Plant. Souvenir lamps with a built-in radio receiver such as "CH-25" and "CH-25P" allow you to illuminate a desk, coffee table or bedside table and receive radio broadcasting stations in the range of long and medium waves. The combination "CH-25" denotes a Table lamp with a 25 W lamp. What the added letter "P" means is unclear. In the first model, the radio receiver is assembled according to the direct amplification scheme on six germanium transistors, in the second on two silicon and one microcircuit. The sensitivity of the receiver is about 10 mV / m in any range, the nominal output power is about 100 mW. This is in any of the options. The range of reproducible frequencies in the 1st version is 300 ... 3000 Hz, in the 2nd - 250 ... 4000 Hz. Souvenirs are powered by 220 V.
