Vintage Tube Amp

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).

Up for sale, a circa 1948 Gibson BR-6 vintage tube amp in excellent condition and in perfect working order. Recently serviced, this BR-6 is the two-input version available from 1946-48, pushing 10 watts via a pair of vintage RCA 6V6 power tubes through a Jensen P10S speaker. The tone is warm and fairly dark in its voicing from 1-5 on the single Volume dial, gaining grit and overdriven roar pushing towards 10. The amp really shines when dimed out with the midrange character unique to octal preamp amps and a real gutsy, punchy sound that’s thick and saturated. The point-to-point circuit has been fully rebuilt with a pair of vintage Hammond transformers, new electrolytic caps and signal caps from the likes of Sprague and Mallory. The speaker is a vintage Jensen P10S alnico magnet driver (replacing the original field coil) with a clean Jensen foil label on the magnet and date stamp on the edge of the dark green frame from 1953. The amp retains its original smooth brown covering, made from the same material used on early’50s Gibson guitar cases. The enclosure is extremely clean, with very minor edge wear, and the textured gold grillcloth is equally as well-kept. The large “G” gold badge is intact central to the grill, and the faceplate has clean silkscreen graphics. Even the original leather handle is present and still viable.

Up for sale, a 1946 Gibson BR-1 combo amplifier in collector-grade condition and in perfect working order. This rare Gibson dates to the earliest days of guitar amplification, produced in limited quantities, with only a few hundred made between 1946-49. This particular iteration is also notable for featuring a green felt stenciled “G” on the aluminum grill, an extremely uncommon feature only seen on select few surviving amps and likely only used in first-year examples from’46. The BR-1 is arguably one of the most important amplifiers of the early days of rock and roll, and was the amp used by Danny Cedrone to record the iconic solo on Bill Haley & His Comets’ landmark Rock Around the Clock, the first rock and roll song to experience significant commercial success. This BR-1 pushes around 12 watts and offers distinct voicings via two Instrument inputs and a single Microphone input. The Microphone input is far and away the most aggressive, quickly pushing into fuzzy, sizzling breakup, while the Instrument inputs have more headroom and retain clean, warm sounds with a very pleasing chug that evokes the earliest days of rock and roll, particularly when paired with a set of single coils. The Tone knob has a limited sweep: rolling it off results in a slightly gentler, spongy sound, and when opening up the control this amp really starts to sing, with a full-bodied sound and just a touch of natural gain. Or, roll off the Tone and crank up the Volume for a thick wooly heft and roar similar to a classic fuzz box, particularly via the Microphone input. The amp retains the original transformer pair, and the power transformer dates to the 17th week of 1946. The original 12 field coil speaker is present, with the output transformer mounted to the speaker frame. There are only a couple modern capacitors in the preamp, and a three-prong power cord has been installed. The tube complement comprises a pair of JAN Philips 6L6WGB power tubes, a Tung-Sol 5U4GB rectifier, and an RCA 6J5 preamp tube. The amp retains its original smooth brown covering with only minor edge wear, and gold “Gibson” text is silkscreened on the top edge of the amp’s face. The perforated metal grill plate is extremely clean, retaining the green felt-stenciled “G” and original trio of brown Bakelite knobs. The original leather handle is also intact.
