Vintage Tube Amp

FEWER THAN 900 EVER BUILT!! Up for sale is an extremely hard-to-find Gibson GA-77 Vanguard (GA-77RVT) combo amplifier – one of the scarcest major-brand tube amps of the 1960s, produced in very low numbers compared to Fender, Ampeg, or even Gibson’s own GA-75/GA-79 lines. These rarely come up for sale in any condition, and far fewer are still fully functional. This one has been recently serviced, recapped, and is ready to play. Why This Amp Is Rare. The GA-77/GA-77RVT was only built in small production runs, and Gibson documentation confirms far fewer were made than the GA-5, GA-8, GA-20, GA-40, or Maestro series. Survivors are scarce, especially with original components and a working reverb/tremolo circuit. These were expensive when new and were primarily ordered for regional pros – not mass-market stores – which means very few original units exist today. Original Jensen Special Design speaker (period-correct and highly desirable). 50-watt class, serious stage volume. Gibson’s highest-end combo of its era. Aluminum control panel, classic Gibson look. Beautiful vintage wood cabinet. Why Collectors Want This Model. The GA-77 Vanguard is widely considered one of the best-sounding and most powerful combos Gibson ever built – and also one of the hardest to find. Most Gibson models of the era had production numbers in the thousands. The GA-77 series had only a fraction of that, making clean examples extremely scarce. If you’re looking for something different than a Fender Twin or Ampeg Reverberocket – something rarer, richer, and historically important – this is the one.

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.

Up for sale, a 1941 Gibson EH-125 1×12 combo amp in excellent condition and in perfect working order. Introduced in’41, just prior to US involvement in WWII, and only produced for a few years, this rare, early Gibson amplifier is the little sibling of the EH-150, pushing 10-12 watts of power via a pair of vintage RCA 6V6 tubes through the original field coil speaker. This amp features three inputs: one Microphone and two Instruments, along with a single Volume control which dictates only the Microphone channel (the Instrument channels are fixed/maxed volume). Tonally, this amp is sweet and smooth, with fantastic clarity and a kind of burnished warmth that one can really only find with the amplifiers produced in the very first days of electric guitar amplification. The Microphone channel, as the only channel with a Volume control, enables the amp to be pushed up into perfectly creamy edge-of-breakup territory, with a bluesy bite and just enough sizzle. The point-to-point circuit features the original pair of transformers (output transformer mounted to the field coil speaker frame), with a few new tubular signal caps installed as needed, and a modern Alpha-branded Volume pot. A couple stock signal caps and many original carbon comp resistors are present, and the power supply has been recapped with high quality F&Ts. A three-prong power cable has also been installed. The tubes are a matched set of vintage RCAs, including the 6V6 power tubes, a 5Y3 rectifier, and a 6SJ7 and 6J5 valves in the preamp. The original field coil speaker is present; the coil has been rewound and the speaker has been reconed. The original coil cover is intact, and there is a 1941 date stamp on the edge of the frame. The enclosure retains its original “rich Cordoba brown” covering, accented by a small Gibson silkscreened logo, with relatively restrained wear considering its vintage. The black metal grill is clean, the latches that hold on the removable back panel are all intact and functional, the original leather handle and leather corners are present, and the original chickenhead knob is intact.

Very cool vintage 1955 Gibson GA-5 Les Paul Junior guitar amp. Amp shows some staining to the tolex, the handle is missing and there is a small rip on the speaker covering. Amp works and sounds great. Very quiet up to 3 o’clock on the knob, it gets a little noisy when dimed but not too bad. It has the early Les Paul Junior script on the plate. There is a very valid reason for people calling these the Champ killer. Amp still has the original 2 prong power cable.

Up for sale, a 1963 Gibson GA-30RVT Invader in great condition, complete with the original footswitch. Please examine the pictures closely for a complete description. This GA-30RVT has a complete vintage tube set and a pair of original Jensen speakers-a 12″ C12R ceramic magnet driver and a 10″ P10R alnico magnet speaker. This amp is surprisingly quiet and sounds great. Cleans are clear and bold. The Reverb is unique and acts as a volume control as opposed to a wet/dry mix. This allows the effect to be heard with the amp volume otherwise at zero (a particularly ethereal sound), and also causes the reverb to have its own natural overdrive characteristics when you crank it. The Tremolo is particularly dimensional and deep with a strong throbbing quality. The circuit is original and professionally serviced only as strictly necessary, with new electrolytic caps and a modern three-prong power cable. All of the original transformers are intact and all of the pots are original as well. This model has 8 Tubes and include a matched pair of Westinghouse 7591 power tubes, a Amperex Bugle Boy rectifier, and original RCA-branded valves in the preamp. The amp schematic appears to be identical to the early and coveted Epiphone EA-12 RVT Futura. The speakers are both original to the amp. In addition, there is a switchable external jack that cuts off the connection to the output transformer, allowing you to easily use this as a stand alone speaker cabinet. The cabinet construction is impressive and the overall unit is unbelievably clean. The amp features its original smooth brown covering and two-tone grillcloth, with a large Gibson badge on the face, almost pristine graphics on the aluminum faceplate, and a full complement of reflector cap knobs. The original (hard-wired) two-button footswitch is included.

Up for sale, a 1957 Gibson GA-20 in excellent condition and in perfect working order. Featuring original two-tone cosmetics, a positively gleaming chrome faceplate, a Jensen P12R speaker, and a very original and 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, 5Y3 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 the preamp retains a trio of original yellow Astrons, the same capacitors used in Fender’s narrow panel tweed circuits, and a key component in the musical nature of those preamps. There are a few modern Jupiter tubular caps in the preamp (which faithfully replicate the design and tonal properties of an Astron), and the power supply has been recapped with high quality F&Ts. The original output transformer is intact, and while it would have originally been mounted to the speaker frame, the transformer has been relocated to the chassis. The source-date code on the output transformer dates to the 14th week of 1957. The power transformer is a modern premium replacement courtesy of Mercury Magnetics, fitted with the original “GA-20″-embossed bell cover. 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 22nd week of’57. The original two-tone brown and fawn covering is remarkably clean, especially considering the fragility of this material compared to a conventional tolex or even tweed. The chrome plating on the faceplate is extremely nice, and the amp retains all of its original black silkscreen graphics. The gold Gibson badge is no longer present on the amp’s face, and the luggage-style handle is present.

Up for sale, a 1962 Gibson GA-79RV in excellent condition and in perfect working order, complete with the original footswitch. A true stereo affair, the GA-79RV features a V front cabinet with two 20 watt channels pushing individual 10 Jensen ceramic magnet speakers. The quad of 6BQ5 (EL84) power tubes deliver a healthy 40 watts of all tube power when run in mono, and these tubes have a crystalline top end and heavenly overdrive, delivering a distinctly Vox-esque sizzle and roar when diming out the circuit. The cleans are snappy and clear too, with appropriate headroom before the circuit cascades into touch-sensitive bite and crunch. Exclusive to Channel 1, the tube-driven Reverb is lush and splashy, and given the stereo operation, the GA-79RV also offers the unique opportunity to mix the effected signal of Channel 1 with the dry signal of Channel 2, with a distinctive cabinet design that fills a room with dimensional tube tone. The circuit has been freshly and professionally serviced, with original transformers and a recap of the power supply with F&T capacitors. The tidy tag board circuit features a bevy of original carbon comp resistors and molded signal caps, and the CentraLab pots have visible date codes from the 38th week of’61. The vertically mounted reverb tank has a date stamp from the 2nd week of’62. The tube complement includes a modern quartet of Sovtek EL84 power tubes, with all vintage valves from the likes of RCA and GE in the preamp. The chrome-plated faceplate has plenty of shine, with all of the original black silkscreened text intact as well as all of the knobs. The speakers have been replaced with a modern pair of Jensen C10Q ceramic magnet 10 drivers. The original footswitch is included too and hard-wired, allowing easy activation of the Reverb, and fitting in its original metal bracket for transport central to the lower back panel. The original textured dark gray tolex and wheat grillcloth are extremely clean, and particularly notable, the entire original plastic Gibson badge is intact central to the face of the amp (a true rarity).
