Vintage Tube Amp

This is a used Knight tube mono amplifier. It is in very good cosmetic condition; see the pictures. It uses EL84 output tubes in push-pull config. It is in stock form and has “phono” and “tuner” inputs. It can be rewired for more gain (it has 2 – 12AX7′s). It has been used recently and it sounds good, playing an entire CD without any problems (CD player was plugged into the “tuner” input). It had a new power transformer installed, but it still does not have a fuse (as it came from the factory). The chassis was painted where the new transformer was installed but the paint does not match the surrounding area. All the tubes tested good on a Sencore TC154 tube tester.

Up for sale, a 1951 Oahu Chicago Model 51, recently serviced and ready for stage and studio use. This early Oahu amp was manufactured in Chicago by the parent company, Valco, who made amps under the National, Supro, and Gretsch brands, among others. Powered by a pair of 6V6 tubes and voiced through a modern Jensen 10″ alnico speaker, there’s a midrange richness and detail to the breakup of these amps that is signature “Valco tone. The bloom, light compression, and creamy nature of the sound reacts well with a variety of guitar pickups and makes this amp a perfect secret weapon for studio sessions, and it really shines with a microphone in front of it. The circuit has been thoroughly serviced by our techs here at Mike & Mike’s Guitar Bar, with new Mallory caps in the preamp where necessary, Sprague Atom filter caps, and a new three-prong power cable. The original Stackpole pots are intact, along with the original transformers. Mounted to the back panel, an external speaker jack has been installed, with an on/off switch to engage or disengage the internal speaker as needed. In addition to the new Jensen speaker, the original Rola speaker is also included. The amp retains the majority of the original white covering, with the exception of the bottom and left side of the enclosure. The black segmented grillcloth is intact and the metal “Oahu” badge is present, along with the original molded handle. Check out our shop “Mike & Mike’s Guitar Bar, ” and please let us know if we can answer any questions! We use double thick boxes, 1″ foam, and industrial 1/2″ bubble wrap to ensure that your amp arrives safely.

Check out this beautifully preserved old Supro! The power-cord is hilariously under-built, which perfectly demonstrates this items original 60′s mystique. The amp works beautifully and the tremolo knob together with the dual glass vacuum tubes produce a classic analog sound that is hard to find today. Unfortunately two plastic knob covers are missing, but this is a simple fix to the right enthusiast. As you can see from the pictures, there is very little damage to the wood and cloth covering the wood. The front speaker mesh is also very weather-free. Please make an offer!

1950′s Valco Supro Chicago 51 Tube Guitar Amp Vintage Vibe. It has that classic, small tube amp sound. Valco made these for many different companies, this one was probably Supro branded (black stripes down the front) but it doesn’t have the front “Supro” decal. Measures 14″ x 15″ x 7.5. At some point someone changed out the grill cloth with the regal looking metallic mesh. The handle is also metal and non original. Otherwise all the tubes and electronics seem to be original. Hope you enjoy it. US buyers only on this fragile item. The item “1950′s Valco Supro Chicago 51 Tube Guitar Amp Vintage Vibe” is in sale since Tuesday, July 3, 2018.
