Since 1982, the "Karavella-203-stereo" transistor network electrophone has been produced by the Kirovsky plant "Ladoga".

Electrophone is designed to play back recordings from mono and stereo records.

The peculiarity of this electrophone is the vertical position of the record being played.
,86e6f450b8cc469628ba70bf2947b049
All this required the solution of technical problems related to the elimination of the influence of the imbalance of the gramophone record leading to a change in the playback speed, increased requirements for the tonearm of the pickup and the disc assembly.

For the EF of the 2nd group of complexity, the solutions that are admissible in terms of costs for the models of the highest group turned out to be unsuitable, so the necessary parameters were obtained differently - using a high-speed system for stabilizing the disk rotation frequency and a tangential arm of the original design.

Karavella-203-stereo differs from other electrophones in a number of new consumer qualities.
,86e6f450b8cc469628ba70bf2947b049
So the direct drive of the disc was used, from a super-low-speed asynchronous arc-stator motor with electronic speed control, a pickup based on a tangential tonearm and a piezoceramic head of the GZK-208 type was used, a stroboscope with built-in illumination and smooth adjustment of the disc rotation frequency, a vernier manual movement device

pickup heads with blocking of working position movement, record holder on the EPU disk axis, record cleaner.

The EF is equipped with two broadband bass-reflex speakers, the LF path is characterized by a low level of nonlinear distortion.

The electrophone has properties for models of the second group of complexity: These are separate volume controls, tone controls for high and low frequencies of sound, mono and stereo switches, inputs and plate format, a hitchhiking shutdown device.
