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.
