Workhorse PowerTube 500 Series Vacuum Tube Mic Preamp

The PowerTube leverages the warmth and tone of a 12AX7 vacuum tube using an innovative non-radiating charge pump that supplies 140 volts to the tube to deliver the excitement and character of a high-voltage vintage tube amplifier. This feeds a class-A balanced output stage that together, can produce as much as 60dB of gain, making the PowerTube ideal for use with all microphones. For even more character, activating the Air switch adds a slight edge to a vocal track or sparkle on acoustic guitar, while low frequency resonance is easily tamed using the high-pass filter.
