Supro Model Tube Amplifier, made by Valco (1950), made in Chicago, serial # V-33106, tweed fabric covering finish. The amplifiers built by Valco in Chicago from the 1930s through the ’60s have maintained a reputation for great sound and solid design over the many decades since they were made, often more so than the company’s guitars. This little amp was Valco’s first post-WWII Supro-branded offering and one of the their simplest designs, sold under the imaginative name “Supro Amplifier”. It was also offered as a set with the earliest postwar plastic-covered steels.This mid-tier combo sports a snazzy period look and solid construction with a woven Tweed-style fabric covering, rounded-corner rectangular speaker cutouts and dark brown plush grille cloth. The grey metal control panel bears white striped accents and a cool Art-Deco graphic around the volume control. The amp features a simple layout of two instrument inputs and a single volume control. A push-pull 6V6 power section puts out about 10-12 watts of power into a 10″ field coil speaker.These early Valco amps are some of the best engineered of their era, and still a great value in a hardwired tube combo. After all Valco was a period leader in electric instruments when Leo Fender was still building amplifiers in a metal shack! This is a typically solid, attractive and well-engineered amp with a great raunchy tone when turned up.Height is 15 in. (38.1 cm.), 14 1/2 in. (36.8 cm.) width, and 7 1/2 in. (19 cm.) deep. This 70+ year old amp is beautifully preserved in very nice cosmetic condition. The Tweed-esque fabric covering only shows very light wear overall. The grille “cloth” is more of a metal mesh that may have had some fabric/fuzz woven on at one point, is intact and shows no holes or damage. The control panel is likewise very clean with only very minor wear. The handle may be original, if not at least an older replacement.Electrically the amp is nicely original, including the 10″ Rola field coil speaker bearing the marking 285-907, dating it to the 7th week of 1949. It appears to retain its original cone and still sounds fantastic. Both transformers are original to the amp, the power transformer bears the marking 16629 and the output bearing the marking 56053. The amp has received our typical servicing and maintenance, including replacement of all electrolytic capacitors, a grounded 3-prong power cord, all sockets, pots and jacks cleaned and biased to spec.This is a neat and still useful gigging amp for lower volume situations, with a great snarly sound for harp or guitar when cranked and quiet enough for recording purposes. Excellent – Condition.
