Portable radios "Spidola-207" and "Spidola-208" have been produced by the State Electrotechnical Plant VEF since 1972. ,86e6f450b8cc469628ba70bf2947b049The portable transistor radio receiver of the second class "Spidola-207" is designed to receive broadcasting stations in the DV, SV and HF bands, as well as radio stations operating in the VHF c FM band. ,86e6f450b8cc469628ba70bf2947b049The main difference between the `` Speedoly-207 '' receiver from the previous model `` VEF-201 '' is the presence of the VHF range. ,86e6f450b8cc469628ba70bf2947b049There are also other innovations aimed at improving the sound quality of the receiver and improving performance. ,86e6f450b8cc469628ba70bf2947b049In the LF amplifier, a LF tone control is introduced, which reduces the current consumption and improves the quality of speech programs. ,86e6f450b8cc469628ba70bf2947b049The level of nonlinear distortion has been almost halved due to negative feedback circuits covering individual stages of the bass amplifier. ,86e6f450b8cc469628ba70bf2947b049The circuit for supplying the AGC voltage to the first stage of the IF amplifier has been modified. ,86e6f450b8cc469628ba70bf2947b049Automatic frequency control has been introduced into the VHF-FM unit. ,86e6f450b8cc469628ba70bf2947b049Control over tuning to the station is carried out by a pointer indicator. ,86e6f450b8cc469628ba70bf2947b049The speaker system of the receiver consists of a 1GD-4A loudspeaker mounted on the front panel of the case. ,86e6f450b8cc469628ba70bf2947b049The receiver "Speedola-207" is powered by 6 elements of type 373. The dimensions of the receiver are 310x200x95 mm, the weight is 3.8 kg. ,86e6f450b8cc469628ba70bf2947b049Together with the 207 model, to expand the range of goods, the plant produced the Spidola-208 radio receiver, which differed only in the absence of a tuning indicator and inscriptions on the case.,86e6f450b8cc469628ba70bf2947b049,null,ru,null,null,null,null
