Rich-sounding tube preamp, 500 Series optimized
When you’re after a dose of warmth and character, the PowerTube preamplifier delivers. Packed into the smart, space-conscious 500 Series format, the fully discrete Radial Engineering PowerTube offers the classic sound of a 12AX7-fueled tube preamp complemented by a Jensen transformer. And with selectable 48V phantom power, the PowerTube puts old-school tube tone at the ready for your condensers and ribbons alike.
12AX7 and Jensen transformer for classic tube warmth
At the heart of the Radial Engineering PowerTube mic preamp is a specially designed 12AX7 tube, coupled with a Jensen transformer. This low-noise, rich-character combination pairs nicely with a wide range of microphones and represents an oustanding value for your 500 Series setup.
Fully variable gain control with metering and more
The PowerTube makes the most out of its compact format, giving you variable input trim and gain control as well as selectable low cut, presence, and 48V phantom power switches. Visual feedback comes in the form of a bright 10-segment LED gain meter as well as a notice light indicating when 48V phantom power is engaged.
Convenient 500 Series format
Canada-based Radial Engineering has embraced the 500 Series format, contributing a range of excellent-sounding (and exceptionally made) tonal tools and sonic options to the popular modular format.
