AmpRX Eurovolt BrownBox Voltage Stabilizer


The AmpRX Eurovolt BrownBox squeezes every last drop of tonal quality out of your classic tube amp. It guarantees an increase in musically rich harmonic content from an amp style that simply doesn't run at optimal levels on modern day's mains voltage.

The Eurovolt BrownBox places your amp circuit into balance. Line level voltage varies by up to 12%, and these excessive voltage conditions make a world of difference to tube amp purists. Voltage correction has been used by amp techs for decades, but now it's easier to optimise fundamental tube tone than ever before.

Here's what AmpRX say about the BrownBox:

Professional recording studios, techs and musicians know that proper supply voltage is essential for optimal Tube amplifier performance. You too can now capture that elusive, classic warm vintage tone with BrownBox.

The basis for any signature world-class tone of course begins with talent, but it also requires a consistent and dependable signal chain, and for that you need to know where to begin. BrownBox provides that consistent basis, guaranteed. Over and over, BrownBox user's testify as to how their amps tone, touch and feel have finally come together providing them with improved harmonics and dynamic amp performance. Take control of your signal chain and begin building a signature world-class tone all your own. Classic tube amp tone begins with BrownBox.
