Vintage Tube Amp

I offer for sale an old Tesla amplifier. The device has not been used for many years, it is in mint condition. I did not turn on the amplifier from the mains to avoid damage. Please see detailed photos. I can send schematics and manuals in Czech language electronically. 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 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. Rated output power/voltage: 8W/100V. Power supply/power: 110, 120, 150, 200, 220, 240V / 70W. Tubes: 6F31 (photon preamplifier), 6BC32 (micro preamplifier), 6BC32 (mixer), 6CC31 (phase reversal), 2x6L31 (final stage), AZ12 (rectifier). I’m sending all over the world!! If you have any further questions, please write to me.

For sale is a rare pair of Tesla BZ202 cinema tube amplifiers made for the Meopta ALMO 16 projector. Comes with a power transformer; not sure how it’s used. The amplifiers were briefly tested. Power comes on on both amplifiers. The wires seen in the photos coming out of the amplifiers were briefly hooked to the speaker output for quick testing and has been removed and is not included. One amplifier reproduced music great and the other had issues producing sound. No repairs were made and all passive components are original. Tubes included are ECH22 (x2), EBL21 (x2), AZ4 (x1). They have not been tested. This item is in the category “Consumer Electronics\Vintage Electronics\Vintage Audio & Video\Vintage Amplifiers & Tube Amps”.
