Designed without compromise, the Wunder Audio Tube Mic Power Supply Unit is the result of complete creative and engineering freedom. Its proprietary design features a high voltage path that runs constant current and balances constant current against a shunt regulator.
The result is a completely clean voltage to the microphone free of RF interference and WiFi interference. Comes in regular version or version with pattern switch. Can be special ordered and configured to run with most tube mics. An optional stereo version is also available.
