The transistor "Phoenix-001-stereo" network transistor since 1975 has been producing the Lvov Telegraph Equipment Plant. Designed for high-quality playback of recordings from stereo and monophonic records and to amplify signals from external sources of sound programs. The EF consists of a high-end electronic control unit OEPU-2C with electronic control, a two-channel amplifier with a six-band tone control and two loudspeakers 20AC-2, each of which contains two low-frequency heads 10GD-30 and two HF ZGD-31. The EPU uses a GZM-105 magnetoelectric head with a diamond needle. Pickup control at start-up with a smooth lowering on the plate, lifting and returning to the starting position after the end of playback is automatic. In the EPU has a hitchhiking, adjustment of the rotational speed of the disk and a device to compensate for the rolling force. The nominal output power of a 2x15 W stereo amplifier for an electronic phone with a SOI of 1.5%. The range of operating AF in sound pressure is 40 ... 18000 Hz. ESD detonation coefficient 0.15%, vibration level -60 dB. Electrophone is powered from an alternating current network of 127 or 220 V, power consumption is 150 W. The dimensions of the microphone are 630x420x210 mm, speakers - 350x680x230 mm. Weight, respectively, 60 and 15 kg.
