Tube Amp Doctor Premium Quality Tubes

Tube Amp Doctor (TAD) is a renowned German brand founded by Andreas Hecke in 1993, specializing in vacuum tubes, amplifier parts, and vintage tube audio components.

While the brand is based and headquartered in Worms, Germany—where extensive quality control, testing, and selection processes take place—the raw vacuum tubes are sourced from specialized tube manufacturing plants located internationally, primarily in China, Russia, and Slovakia, before being tested, matched, and branded in Germany.

The brand is privately owned and operated by its founding entity, Tube Amp Doctor Musikhandels GmbH.
