Heathkits were products of the Heath Company, Benton Harbor, Michigan. Their products included electronic test equipment, high fidelity home audio equipment, Black & White and Color TV receivers, amateur radio equipment, and the influential Heath H-8, H-89, and H-11 hobbyist computers, which were sold in kit form for assembly by the purchaser. Today, audio kits are known as DIY audio ("do it yourself" audio).
