Vintage Challenger Model CH30 tube amplifier from 1940′s. Originally designed as public address pa system amplifier.

Beautiful 1961 Bogen Challenger CHA-10 Vintage amplifier. Completely restored plug and play ready! Glorious single ended 6L6 sound! Think way louder Fender Princeton. Amp is mostly stock with a few useful mods. The tone switch has been changed to way more useful tweed Fender tone pot circuit. The phono pot is now a master volume. 1/4 input and speaker out jacks. 4, 8 and 16 ohm outputs. I added a 3 prong power cord and fuse for safety. Still has the original hang tag from the power cord! All original high testing Bogen tubes-6AV6 (Blackburn Mullard), 6AU6 (RCA), 6L6GC (GE) and EZ81 (Blackburn Mullard). I haven’t done one of these for awhile, so video is of one I did while ago the same way so you can hear how it sounds.

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.
