Vintage Tube Amp

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.

Vintage Magnavox AMP 101-B Tube Amplifier with Original Field Coil Speakers. Unit was brought up slow on a Variac and powers up fine. The 6V6 output tubes when tapped or rubbed with fingers become microphonic enough to be heard through both speakers. No further testing has been done. One speaker has a small cone tear as can be seen in pics.

International buyers, please wait for invoice before paying. This is from my personal collection. More premium vintage gear coming soon! This listing is for the 2 amplifiers pictured. They are priced to sell, super super cheap for this quality! Here is a super pair of Baldwin D520-10H 40 Watt field coil amplifiers from 1950! Holy Smokes, look how clean these are! These have been in my collection for decades and I have always kept them in a heated and air-conditioned building! The serial numbers are 7251 and 7253. These were made almost one after another on the assembly line. Each amplifier uses: (4) 6l6GC, (2) 5U4G and (1) 6SN7GT. Tubes are not included. I used these amplifiers years ago and they worked great. I have not had them on in a while, transformers are guaranteed, and I would recommend a quick recap to bring these back to these full glory! These amplifiers really sound great. We ran these on a pair of extremely old field coil Lansing speakers and just loved them. I’ll never forget that light airy sound with stereo imaging that I just haven’t heard of since. Great to find a wonderful stereo pair in such wonderful condition. The red manual IS NOT included! We use all brand new boxes and packing material from Uline. Each amplifier will be packed separately, so you will receive 2 boxes.

THIS COMES AS PICTURED AND UNTESTED. I BELIEVE IT IS A 2-CHANNEL POWER SUPPLY BUT THE PARTS IN IT ARE VERY NICE AND COULD BE USED IN AN AMPLIFIER BUILD.
