Up for sale, a 1965 Harmony H420 tube amp, a rare Valco produced and USA-made alternative to the famed Supro Thunderbolt! Produced in the same Valco factory as the Thunderbolt and marketed by Harmony to pair with their guitar line, the H420 is extremely similar in terms of circuit and layout to its more famous Supro cousin, with the added benefit of individual Treble and Bass controls. Rich, powerful, and nuanced, the H420 pushes 35 watts through a pair of original RCA 6L6GC power tubes and the original Jensen C15N speaker. For everything from clean, 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 circuit is completely stock, with CTS pots that date to 1965 and original impressively sized transformers as well. The faceplate retains its original shiny chrome appearance, with all of the original black silkscreen graphics and lettering, as well as a minty trio of stock witch hat knobs. The Jensen C15N speaker has a near mint black speaker frame, gold foil label on the ceramic magnet, and date code from’65. The original black ostrich tolex is extremely clean too, with only a few requisite scuffs and light marks of wear on the edges of the enclosure. The H420 is a great workingman’s amp for half the price of a Supro Thunderbolt! Check out our shop “Mike & Mike’s Guitar Bar, ” and please let us know if we can answer any questions!
