KZ 8 TESLA 513000 Description: Amplifier for amplifying acoustic frequencies supplied by a microphone, gramophone record, photon of cinema equipment, etc. Either one larger or several smaller speakers can be connected. Basically, it is a four-stage amplifier with a symmetrical output stage. A special pre-amplification stage is built in for the photon. By changing the frequency response with the control elements, the amplifier can be adapted to each type of transmission in order to achieve a high quality of reproduction. The amplifier can be used both in the home and in industry and in various establishments. At home, it can work as an amplifier for a record player, so better reproduction can be achieved than with a radio receiver. In a restaurant, it can be used to cheer up and entertain guests, to call guests to the phone, etc. In industry, various uses can be found where the sensitivity and power of the amplifier are sufficient, for example during various measurements, checks, in laboratories and in operation. For small telephone transmitters up to 15 to 20 W, the amplifier is used as a very good modulator. Manufacturer Tesla Pardubice. Wire connections. Rated output power/voltage: 8W/100V.
