Heathkit EA-2 amp chassis of a early 60’s mono amplifier.This design is for a 12 watt mono amp of a push-pull circuit design using EL-84 tubes.Make no mistake NO tubes are included in this sale, this is only a Chassis.Dimensions 12.5 w, 8 3/16 d, 4 3/8 h.Weight 15 lbs.
US$50 looks like a solid buy for a Heathkit EA-2 if it’s complete and not obviously hacked up. Comparable examples tend to land well above that once they’re tested, restored, or even just clean and presentable, so this is below fair market for a known-good piece and very much in bargain territory for a mono tube amp with collector appeal.
The EA-2 is a well-regarded little Heathkit: simple, attractive, and a good entry into vintage tube sound with enough parts availability and documentation to keep it practical. The upside is strongest if it’s original, has its tube complement, and the transformer covers and chassis are clean; even nonworking, a complete one at this price is attractive. Only pause if it’s missing iron, heavily modified, or described as parts-only.

Heathkit traces its origins to 1911 in the United States, when Edward Bayard Heath founded an aircraft company in Chicago after acquiring the Bates Aeroplane Co. Renamed E.B. Heath Aerial Vehicle Co., it pioneered kit-built planes like the 1926 Heath Parasol. Following Heath's death in a 1931 test flight, Howard Anthony acquired the bankrupt firm in 1935, shifting focus to aircraft accessories in Benton Harbor, Michigan. Post-World War II, Anthony pivoted to electronics in 1947 with surplus parts, launching the iconic O-1 oscilloscope kit for $50—a bestseller that birthed the Heathkit brand and its DIY ethos.
In hi-fi audio, Heathkit earned acclaim for tunable amplifiers, integrated receivers, preamplifiers, tuners, and speaker systems, all sold as meticulous assembly kits from the 1950s through the 1970s. Standouts included the AA-151 and A-7E power amps, known for their robust tube and solid-state designs, alongside full stereo systems like the AR-15 receiver. The brand expanded into test gear and amateur radio but prioritized high-fidelity components for home enthusiasts.
Heathkit occupied a mid-tier market niche, delivering exceptional value through user-assembled kits that rivaled factory-built rivals at half the cost. Prized for reliability, customization, and warm sound signatures, these vintage pieces command collector status today among audiophiles restoring "kit-built" icons. Though production ceased in the 1980s after Zenith's acquisition, Heathkit's legacy endures as a cornerstone of DIY hi-fi heritage.
