Here we have a beautiful 1947 Gibson BR6 amp. This is the much rarer 1st edition that was only made for a couple of years. This amp is in very nice shape considering it’s close to being 80 years old! Fully restored with the top notch parts! Plug and play ready! All of the caps have been replaced with Blue Sozos and F&T electrolytics. New Carbon comp resistors where necessary. 10 Rola field coil speaker is in great shape and sounds awesome! I had to replace the input jacks and the volume pot due to unusable originals, Switchcraft jacks and CTS pot. Mods to the circuit, I changed the volume pot to go after the first gain stage instead of coming right off the input jacks and I hooked up the input jacks to be a Fender style hi/lo configuration instead of both being the same. High is the top, low on bottom. Tubes are all high testing vintage-Sylvania JAN CHS 6SL7GT, Sylvania 6SN7GT, two Sylvania 6V6GTs and RCA 5Y3GT. I think all of the tubes but the 6SL7 are the original tubes. The 6V6s are 2mA apart in circuit. Here’s your chance to get a true classic! Video is of last one of these I did the same way for reference.

Completely restored 1948 Gibson GA25 vintage tube amp combo. This amp sounds truly heavenly! Original Jensen 12″ and 8″ alnico speakers have been reconed by the good guys at the Circuit Shop. Both have early’48 date codes. All out of spec parts have been replaced with highest quality parts. Red Jupiter coupling caps. Sprague Atom and CE electrolytics. Carbon comp resistors on the few that were actually out of spec. Both pots have been opened and thoroughly cleaned and lubed. Still has the screw on shield for the inputs that most of these are missing. The wiring going to the speaker mounted output transformer was starting to crack in places, so I covered the 3 wires with heat shrink tubing for safety. 3 prong power cord. All vintage tubes, two-6J5s and 5Y3GT which I believe to be original RCAs, RCA 5693, which is the ultimate 6SJ7, and two Sylvania 6V6GTs. All test very good on my calibrated Hickok 6000A. The 6V6s are perfectly matched in circuit. Amp will be professionally packed up by UPS Store. First half of video is with volume halfway up, second is fully cranked.
