1967 Harmony 525 Vintage Tube Amp 1×15 Supro Thunderbolt with Jensen C15P, Valco
Up for sale, a 1967 Harmony model 525 tube amp in excellent condition and in perfect working order. Made in Chicago, USA by Valco (the parent company known for producing the Supro, National, and Airline brands among others), the 525 is essentially a Supro Thunderbolt with the added benefit of individual Treble and Bass controls. Rich, powerful, and nuanced, the 525 pushes 35 watts through a pair of original RCA 6L6GC power tubes and an original Jensen C15P speaker. For everything from rich cleans and wooly rhythm tones to saturated tube overdrive further up on the volume dial, this Harmony delivers a pure sound with a simple yet ingenious circuit. The signature sizzle, drive, and subtle compression of Valco/Supro’s preamp design offers a very dynamic and articulate signal balanced by the warmth and fullness of the single 15 speaker. The circuit is very original, with CTS pots that date to 1967 and original impressively sized transformers as well. The faceplate retains its original gleaming chrome plating, with all of the original black silkscreen graphics and lettering, as well as a minty trio of chrome insert knobs. The Jensen C15P speaker has a near mint black speaker frame, gold foil label on the ceramic magnet, and date code from’67. The original black ostrich tolex is extremely clean and the grill cloth retains its vivid red racing stripes. The Valco-made Harmony 525 is a classic, oft-overlooked model with the same preamp, tube and speaker compliment, and rich tone as the Supro Thunderbolt.
