Vintage Tube Amp

1966 Harmony H440 Vintage Tube Amp Valco-Made Supro Thunderbolt 2×12 Jensen C12P

Up for sale, a 1966 Harmony H440 tube amplifier in exceptional condition and in good working order. Like all top-tier Harmony amps of this era, this amp was produced by Valco in the USA, parent company of Supro, National, Airline, and others. Both visually and sonically impressive, this massive 2×12 combo amp was Harmony’s most expensive offering of the era and extremely rare in any condition. Essentially a Supro Thunderbolt with dual 35 watt output transformers and a gigantic power transformer to sum the two sides, this amp is utterly unique and extremely powerful. Top it off with two matched pairs of vintage RCA 6L6GC power tubes and dual rectifiers and you’ve got one very cool amp. The original Jensen C12P speakers accentuate everything we love about vintage Valco preamps, with a color and tone stack that is unique in the vintage amp world. Nothing has the full, harmonic rich overdriven qualities of a vintage Valco amp and the H440 is one of the most revered circuits, with the quintessential Led Zeppelin tone. The tremolo also has a very strong chop to it and the reverb (from the small two spring tank housed in the original cardboard box) has a lo-fi, surfy quality that is ideal for’60s garage and psych tunes. The circuit is very original, with stock transformers and a virtually untouched preamp. An example of true point-to-point wiring, the amp retains its original tone caps and has CTS pots that date to early’66. Tube rectified and pushing roughly 70 watts through two pairs of 6L6GC power tubes, the amp boasts particularly large transformers given its output, and this adds tremendously to the power and punch that the H440 can deliver. A modern three-prong power cable has also been installed. The speakers are the original matched pair of Jensen C12Ps with clean black frames, original gold foil labels on the magnets, and date codes from the 8th week of 1966. Cosmetically, this amp is very clean especially given its size. The black silkscreening on the faceplate is very vibrant and mostly intact, and the chrome shines like new. The original tolex has the “ostrich” pattern seen on some’60s Supro amps and the stock grillcloth shows only limited aging. The polished chrome faceplate is also particularly free from wear.
