TELEFUNKEN Elektroakustik’s premium power supplies feature the traditional styling of vintage Austrian models, partnered with the improvements of modern component technology and circuit board design. Modern improvements include a slow-ramping filament voltage to extend tube life and full regulation to ensure the microphone will always operate the same, regardless of line voltage variations or location. Full regulation also means that stereo power supplies can also power only one microphone at a time at correct operating voltages.

TELEFUNKEN Elektroakustik power supplies are hand-built in South Windsor, CT, USA with premium components including Signal Transformers, Nichicon capacitors, Neutrik and Binder connectors, double-thick circuit boards for structural integrity, and a PCB layout made to maximize current handling. These units are built well over-spec to ensure reliability and safe operation for decades. Each power supply is calibrated to the specific microphone system it comes with. They are burned in as a full unit to ensure optimum performance and operation.
