Vintage Tube Amp

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 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.

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.

When you receive an item, open the package using a box cutter and be mindful not to tear up or throw away the box or any internal packaging. Without having to curb your enthusiasm of basking in the glow of your new piece of gear, think in terms of preserving it in its mint condition until certain you are keeping it. For instance, if it were rack gear, we would recommend avoiding racking it until you were certain it was a “keeper”. Thus preventing any possible “rack rash” or scratches. If it were a guitar pedal, avoid sticking Velcro on it and mounting to your pedal board until it passed your test to be knighted and sit at your round table of pedals. Although tempting to have both of your favorite things together, put down the chicken wings slathered in barbecue sauce that is dripping all over your leather vest and beard and be sure your hands are clean and dry before trying out your awesome new gear. Pet odors, cigarette and other smoke items can also affect the “newness” of your gear. Also, keep the gear away from your friend with the Billy Ray Cyrus mullet driving the Camaro. He’s a good guy and he means well, but years of smoke tar and beer bongs have dulled his perceptions. Incorrect voltage, self-repair, exposure to extreme temperatures, moisture damage, or incorrect application, etc. Earphones, microphones or other items that have intimate mouth, face or body contact. Software, computer hardware, computer drives and other digital or media tape. Items that are special orders, discontinued, or closeouts, are all non-returnable. HOW TO RETURN YOUR ITEM.

Vintage 1950s Gibson GA-20 amplifier. Found this at a local estate. The cord is brittle. I shortened for a brief test. I found it to work but has a hum. Put in a new old stock 5y3 and matched 2 sylvania 6v6 power tubes. Pre tubes are good but lower end off the shelf guitar amp tubes. I pulled the speaker and the cone is great. I cleaned the bell and blew out the dusty inside. The instrument gain pot shaft is a little bent. Looks like one of the chicken head knobs was replaced by a black one at some point. You can also see a piece of wood fell off at some point. I wish this amp could tell its story.
