Up for sale, a 1963 Ampeg Jet J-12-A vintage tube amp in perfect working order. Not to be confused with the numerous “Jet” reissues offered by Ampeg over the decades, this is a genuine original J-12-A, freshly serviced by our techs here at Mike & Mike’s Guitar Bar and converted for use with 6V6 power tubes. The tone is thick, complex, and clean, with a surprising amount of headroom and punch. Of course maxing out the volume can yield everything from a throaty overdriven roar to fizzy sizzle, and the character of the overdrive can be easily sculpted with the tone control. Top things off with a thick, throbbing tremolo and you have a very impressive amp. The chassis has clean chrome plating with original transformers. The stock CTS pots have visible date codes from the 37th week of’63 and the preamp has been fully recapped to ensure optimal performance. The multi-section can capacitor is original and still functions as intended. The tubes consist of a matched pair of 6V6 power tubes, two octal RCA 6SL7 preamp tubes, and a Sovtek 5Y3 rectifier. Cosmetically, this amp retains the original blue checker tolex and silver sparkle grillcloth with a modern leather handle. The cabinet shows some wear on the back panel and corners. On the chrome faceplate, the majority of the original white silkscreen lettering is also intact.

Up for sale, a 1954 Gibson GA-20 in excellent condition and in perfect working order. Featuring original two-tone cosmetics, a Jensen P12R speaker, and a professionally serviced circuit, this GA-20 is the perfect mid-size combo from the golden age of tube amplification. In many ways analogous to Fender’s narrow panel tweed amps of the same era, the GA-20 features a four input design with a 6V6 power tube pair, 5Y3GT rectifier, and dual triode (12AX7, etc) tubes in the preamp. Offering distinctly different voicings between the single Microphone input and the three Instrument inputs, the GA-20 is at its most aggressive via the Mic channel. While this input does offer a modicum of clean headroom, it quickly overdrives with a sizzling, chewy sound that’s extremely smooth. The Tone control has an absolutely massive sweep, actually adding a bit more gain when turned up. Maxing out both Volume and Tone knobs yields a ripping, cutting sound that interacts equally well with single coils and humbuckers. The Instrument inputs have more range in the clean signal, with a full-bodied and sweet sound that works well with a host of effects pedals. Turning down the Tone knob on this channel and pushing the Volume can achieve a very nice bark and a spitty quality almost akin to certain fuzz boxes, depending on the guitar being used, and once again diming everything out delivers plenty of richness and roar. The point-to-point circuit has been professionally serviced and thoroughly recapped with premium tubular signal caps in the preamp and F&T power supply caps. The output transformer has been replaced with a vintage-accurate Mercury Magnetics ToneClone GA20-O, mounted to the speaker frame, while the original power transformer is intact, mounted to the back of the chassis. The speaker is the original Jensen P12R alnico magnet driver which has a dark blue/green frame. The speaker has been recently professionally reconed, and the date code on the edge of the frame is from the 9th week of’54. The original two-tone covering exhibits limited wear (particularly when considering the fragility of this material compared to a conventional tolex or tweed), primarily concentrated around the edges, and half of the gold Gibson badge is still intact on the amp’s face. The graphics on the brown faceplate are clean, the brown chickenhead knobs are present, and the leather handle has been replaced.

EICO HF-89 stereo tube amplifier – Complete bench test and serviced. This amplifier includes everything as shown including all tubes, Wireworld power cord, speaker wire adaptors, and even a bottom plate not shown in photos. Note that all capacitors and resistors were replaced as needed by a qualified technician. Also note that RCA inputs were added. In my opinion this updated vintage factory built amplifier betters most attempts to copy vintage gear and by far betters Chinese attempts.
