AmpRX Brownie Tube Amplifier Input Voltage Attenuator

The AmpRx Brownie is the latest innovation in voltage optimization, providing musicians with unparalleled control, flexibility, and protection for their gear. Hand-wired in Nashville, Tennessee, the Brownie is a voltage optimizing power supply designed specifically for modern tube amplifiers, offering the ultimate solution for achieving consistent tone and protecting valuable equipment - the first of its kind.

AmpRx is the trusted name in voltage control, known for its flagship product, the BrownBox. Designed to protect and enhance amplifier performance, AmpRx voltage optimizing products are used by some of the biggest names in the music industry. With the introduction of the Brownie, AmpRx continues to innovate and expand its reach to musicians everywhere. Let the Brownie transform the way you experience your tone and gear.

WHAT MAKES THE BROWNIE SPECIAL?

Brownie is the first product in the AmpRx line to both decrease and increase voltage and is compatible with all amplifier types from classic tube amps to modern designs. Achieve consistency in tone and protect gear in any environment by dialing in the voltage you need every time you power your amp - love your tone at 117V... you got it! Mitigate disaster with Brownie by protecting your amp from mismatched voltages, avoiding unnecessary, expensive, and frustrating repairs.

WHY IS CONSISTENT VOLTAGE SO IMPORTANT?

The tone and performance of all tube amplifiers rely heavily on the input voltage available from the wall or other power source. Variations in input voltage can drastically affect overall sound and performance and can shorten the life of the components, leading to excessive repairs and frustration.

While 120V is the expected standard, typical variance in homes and commercial buildings like music venues and recording studios can range from 115V to 130V. That’s not safe for an amplifier, tubes, or tone quality. Depending on the amplifier or gear, a player might discover that modern gear runs optimally at 117-120V, or as low as 108-110V for vintage gear. It’s impossible for an amplifier designed for 110V or even 120V to sound or operate anywhere near the way it should at 125-130V.

AmpRx products are adjustable AC power supplies for amps and tube gear that allow the user to discover and supply the optimal input voltage for their equipment, get a tone they love, and protect their gear in any environment, regardless of the normal variations in voltage.

When a tube amplifier is supplied with the proper line voltage, it will sound and respond as originally intended, revealing the circuit’s true harmonic content, and preventing unnecessary, expensive, and frustrating repairs. Players around the world trust AmpRx to safely power their gear and testify time and again as to how their amp’s tone, touch and feel have finally come together, providing them with improved harmonics and dynamic amp performance- allowing them to capture the elusive tone they’ve always wanted, every time, everywhere.
