Vintage Tube Amp

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.

Here are some specs…. This Gibson Hawk is in very good shape, Needs TLC. Included is the original foot-switch to control the effects. In addition there is also a Monitor output jack, and the power switch has 2 positions for polarity change. This amp features the later 2×10 speaker configuration and the later 7591 output tubes. Everything else appears original. These 25 watt “Hawks” have a nice clean tone until you push the front end, then it gets “grittier”. The preamp section is very mild mannered. So the amp doesn’t start to open up until about 7-8. But it will happily take anything that your favorite boost or overdrive or compression pedal will give it. This will give the front end any additional drive you may want. The accordion input is a bit hotter than guitar input. Channel one is working great. Channel 2 needs trem pot, reverb and tremelo serviced or play as it is.. You don’t see them very frequently, and they have a genuine “cool factor”.
