Here’s a really cool tube amplifier. It has mic (or guitar) level input and also line-level input. The phono-plug mic-level input has sensitivity 0.02 V for full output and the RCA line-level input has sensitivity 0.3 V for full output. A two way speaker system in the front which sounds awesome and is really fantastic with a vintage microphone. There’s certainly some potential here for a busking guitar amp or a harmonica amp. All the electrolytics were replaced with F&T or other high quality replacements, Coupling capacitors were replaced as well. No more leaky drifting wax caps. They are well testing vintage tubes. A 6X4 Rectifier, 6V6 Power tube and 12AX7. It operates without issues. Its been brought up to electrical safety standard with a grounded AC cable and a fuse holder was added. These were not fused from the factory. It’s sure to leave you with a repair bill soon after.

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.

There is just one tube included a 5R4 rectifier. Just acquired a massive lot of gear, will not be spending time per unit to acquire parts/tubes and/or have serviced. May work amazing, may need parts, service, repair, restoration, calibration etc. Will be packed well, but will be expensive.

The 1956 Fender Champ Amp Tweed Vintage Tube Amp is a classic guitar amplifier known for its vintage look and iconic Fender sound. With its iconic tweed covering and tube technology, this amp delivers warm and rich tones perfect for any guitar player looking to add a touch of vintage flair to their sound. The Fender Champ model is beloved by musicians for its high-quality construction and timeless design, making it a popular choice for both studio recording and live performances. Amp is vintage and has not been serviced as far as I can tell. Turns on and is functional. Comes with two additional tubes (5Y3GT and 6v6GT). Please see all pics.

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.

Up for sale, a 1964 Vox AC50/4 Mk III vintage tube amp head in excellent condition and in perfect working order, freshly serviced with an extremely original circuit. This UK-made JMI AC50 is a real powerhouse, and the dual EL34 design has plenty of British sizzle and chime, with big, bold overdrive when diming it out, and tight, punchy low end thanks to the diode rectification. The amp pairs exceedingly well with all manner of guitars for iconic British Invasion-worthy tonalities. The circuit is extremely original and freshly serviced by our techs here at Mike & Mike’s Guitar Bar. All of the original transformers are intact, along with all of the original pots, and a preamp that retains virtually all of the original signal caps and resistors with Mullard mustard caps that date to the 3rd quarter of’64. There are two larger capacitors in the power supply to ensure optimal functionality, and the power cable has been upgraded to a modern three-prong variety. The tube complement includes a pair of Ruby EL34 power tubes, with a few original UK-made Mullards in the preamp. The head cabinet retains the original black basketweave tolex paired with the original lattice diamond grillcloth and white piping. The pack panel features dual multi-pin jacks and 8/16 ohm functionality, and adaptor cabling is included to convert the outputs to conventional 1/4 jacks. The blue/gray faceplate retains all of the original chicken head knobs, and other small yet meaningful original parts include the original plastic handle, raised Vox logo, one-pin corners, and model/serial number badge on the back.
