Josef Zellner - Dual
Dual's beginnings can be traced back to 1900 when brothers Christian and Joseph Steidinger began manufacturing watches and turntable parts. Ten years later, the Gebrüder Steidinger company began manufacturing power supplies to allow turntables to operate using mains electricity. It was not long before Dual started making their turntables. After the war, they became the largest manufacturer of this type of equipment in Europe, employing over 3,000 people in several factories. Later the brand expanded to offer customers complete hi-fi systems with amplifiers, tuners, cassette players, and speakers.
