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!!

Awesome 65 blackface vibro champ. This is a awesome sounding little amp that is dripping with the old vintage fender mojo, this sweetie has been in my amp line up for some time and she just don’t get out as much as she should so I’ve decided to re-home her. All works correctly and has had a service check up and new jj tubes recently and I had a 3 prong ground plug installed for safety. Pots are dated 8th week of 65 and transformer is dated 40th week of 65. These amps are only increasing in value I was informed that it is a newer silverface vintage cabinet but is indeed a 1965 chassis so it’s not a 100% original amp but it’s still a great investment.. If any questions feel free to reach out thanks for looking!

[Product name] FLIP-1500 / MODEL GA-1500. [Size] Width: 45cm Depth: 25cm Height: 40cm Weight: 16.2kg. Please note that the measurements are taken by an amateur. The speakers are genuine. There are no accessories included. There were no problems when it came to sound, but I cannot answer questions about the names of the vacuum tubes or their condition. I couldn’t detect any crackling that would interfere with playing, but since this is a vintage amp, I wouldn’t recommend it to those who are sensitive about such things. As sound is a matter of personal preference, I will refrain from commenting on it, but this was a product that was highly acclaimed as a domestically produced vacuum tube amplifier at the time, and it is still one of the vintage amplifiers with many enthusiasts today. The texture of the distorted sound reflects the trends of the time when it was released, so some people will like it and some will dislike it. I think the best choice is to use it in clean mode to enjoy the unique characteristics of a vacuum tube amp, and combine it with modern effects as needed. International Buyers – Please Note. Thank you for your understanding. If you have any questions, please send us a message at anytime.

Vintage Model CH30 Challenger 5 Knob 6 Tube Amplifier 1940s? Pictures with tubes and knobs installed and removed so interested buyers could see condition in those areas. Tubes all seemed to match the numbers imprinted on the amplifier. In vintage used and untested condition with signs of use and wear. Has scratches, paint loss, some rusting, the one piece of detached speaker cord/connector looks very worn. Corners all have paint loss and scratches. Baseplate under the wiring has a fragile paper schematic partially glued or stuck to it. I replaced two missing screws on the cover and one screw in the baseplate. Power cord is approximately 6.5 feet long. I had read somewhere if you are unfamiliar with tube radios/amps that you are better off not testing them because you could damage the unit? Unsure if that is true or not but for that reason I have not plugged this in. Please be your own expert when determining completeness and correctness of this piece. I do my best to explain what I see. See photos for condition.
