Kuprox 1927 Technical Data and Information of General Interest Detailed description and application information for the Kodel Radio Corp.'s copper oxide rectifiers. Their slogan: "No Bulbs · No Liquids · No Noise". This technology was one of the first "metallic rectifiers", which was followed in the late 1930s (in Germany) and 1940s (elsewhere) by selenium rectifiers. Bulkier and not as efficient as selenium rectifiers, but were more stable. Their advantage was no fragile glass bulbs (gas/mercury rectifiers), no messy and corrosive liquids (electrolytic rectifiers), and no noise (vibrators or motor-generators).
