Product Description
In the United States, you should be receiving 120V AC from the wall. But depending on where you are and what time of day it is, you can receive anywhere from 120V to 129V. That’s not good for your amplifier, or your ears. The AmpRx BrownBox is an adjustable AC power supply (a voltage controller) for your amp or tube gear that helps you run your equipment at the optimal voltage. Just plug the BrownBox into the wall, adjust the voltage and then plug your gear into the BrownBox. Simple!
Depending on the amplifier, a BrownBox user might discover that modern gear runs optimally at 116-118V, or as low as 108-110V for vintage gear. It’s impossible for an amplifier designed for 110V or 120V to sound or operate anywhere near the way it should at 129V.
The BrownBox features flexible voltage reduction options that let you bring your power input down to an optimal level, resulting in significantly improved amplifier performance.
Please note that the AmpRx BrownBox is only compatible with amplifiers from the US.
