      Radial Engineering PowerTube 500 Series Tube Preamplifier (108271230)
Availability:  


100% Discrete class-A with Jensen transformer.

The Radial PowerTube is an 'old school' 100% discrete class-A vacuum tube microphone amplifier intended to capture the essence of the voice or instrument while adding the rich harmonics, warmth, and character of a transformer coupled tube circuit.

Designed to fit inside the Radial Workhorse and other 500 series racks, the 'single-wide' PowerTube begins with an ultra low-noise Jensen input transformer. This exhibits near perfect frequency response while producing the warm Bessel curve Jensen is legendary for. The signal is then amplified via a select 12AX7 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. This makes the PowerTube ideal for use with all microphones.

Features include an easy-access front panel XLR input with a safely recessed 48V phantom power switch. To optimize signal-to-noise the PowerTube is equipped with fully variable trim and gain controls. A 10 segment LED bar graph provides visual feedback and driving the PowerTube into the red is encouraged. This increases the grit, harmonic content and distortion. For even more character, activating the Air adds a slight edge to a male vocal or sparkle on an acoustic guitar. Low frequency resonance is easily tamed using the high-pass filter. For added pleasure, the PowerTube comes factory-loaded with a select 12AX7 tube along with a second Tonebone distortion pedal tube for more grit and madness.

Radial Engineering PowerTube 500 Series Tube Preamplifier Features:

  • Single wide module fits all 500 series rack formats
    High voltage 12AX7 tube drive with 60dB of gain
    Smooth sounding Jensen Transformer input
    Hand inserted 100% discrete class-A electronics
