1950′ vintage gibson Ga-20 tube guitar amplifier just recapped sounds amazing reissue speaker. The original speaker was rotted and had tears ready to go no issues.

Check out this mid 50′s Magnatone Starlet amp that I hot rodded into a Fender narrow panel tweed champ! Originally the starlet is an ACDC amp with no power transformer. These typically sound kinda weak, SO I gutted the circuit and added a vintage new old stock stancor power transformer from the 50′s, kept the original speaker and output transformer and built a narrow panel 5f1 champ circuit inside! The results is a super hot rodded maggy! TONS of hot gain and sounds fantastic with every single guitar. Great for low output guitars too like a kay thin twin etc because it has so much gain! The video I made with les paul is only on 3! Grounded cable ALL new caps and resistors. Original cab is in fantastic shape and even has most the original waterslide decal on the front. I have never seen a starlet in this nice of shape. Lots of natural wear and tear. Original button alnico speaker that works great but I cannot promise how long it will uphold if you abuse the amp with pedals or put a metal guitar through it. Watch the video and see how awesome it sounds! This is a killer piece!

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.

Very cool looking unit. Power cord needs replaced for sure. It powers up, the tubes light up inside and out. There’s some paint splatter on it that came off with a little effort. I think it’s latex (try Windex or ammonia) and it’s mainly on the rear of the unit. There is some kind of glue on the front lower area where there is also a chip. I didn’t clean this up much as you can tell by the photo of the inside and the dust. Thanks for stopping by!

Overall condition is good- no damage, just some dust, rust, and patina. All tubes are include aside from the four 6550. This is the most robust and powerful amplifer ever made by Western Electric / RCA. These were designed as monoblock amps, class AB, made to power Voice of the Theater speakers, and the like. These are extremely hard to find in recent years, their price and value ever climbing! This will be packed with exquisite care, using double-walled boxes and robust foam wedges and blocks. Tubes will be removed and packed separately, everything with ample protection. Please also feel free to message me if you have any questions.
