For sale is an original vintage wooden spool wound with enameled copper magnet wire, most likely dating from the 1930s. The wire measures approximately 0.15 mm diameter and the remaining length is estimated at around 50 metres.
A rare and attractive item for collectors of German industrial history, vintage-radio enthusiasts, transformer winders, and audiophile DIY builders seeking period-correct material for restoration or experimental projects.
Kabelwerk Rheydt was founded on 28 February 1898 in Rheydt, now part of Mönchengladbach, Germany. The company initially produced copper telecommunications cable and became an important participant in the German cable industry during the early twentieth century. In 1935, Kabelwerk Rheydt acquired a majority interest in Deutsche Kabelwerke AG of Berlin.
In 1972, Kabelwerke Rheydt AG merged with Vereinigte Draht- und Kabelwerke AG, Berlin. This spool therefore represents material from the company’s earlier, independent historical period—well before that merger.
Subject to inspection and electrical testing, this fine vintage copper wire may be useful for:
For audiophile restoration work, old-stock wire can be especially appealing where a historically authentic construction is desired. However, no sonic advantage over modern, specification-matched copper magnet wire is claimed. Final performance depends on winding geometry, turns count, core material, DC resistance, insulation condition and workmanship.
An appealing piece of pre-war German electrical-industry history for vintage audio restorers, transformer winders and collectors in Japan, South Korea and the United States.
Please note that this is genuine vintage wire. The wire diameter and remaining length are approximate.
