   The Brown Box Voltage Regulator from AmpRx lets you “brown down” the voltage powering your amp. This is not an attenuator, but rather a power supply that can dial in the correct voltage for your vintage amp. Most vintage amps actually sound better running between 105 & 110 volts versus the 125 volts coming out of your household wall circuit.

   Apr 6, 2024 · The Brown Box is more like a step down transformer and not a voltage regulator. So if your voltage is fluctuating without the Brown Box, it'll fluctuate after it, just at a lower selected voltage range. So that was the issue I was having at my house where my voltage can go from 116-127V in a matter of an hour and then up and down all day.

   Oct 5, 2018 · This made me think a bit. I hadn’t really considered that the amount of voltage feeding your amp could change your tone. I also found out that voltage can vary from outlet to outlet. It can even change intensity on the same outlet throughout the day. In my Brooklyn apartment the voltage can go anywhere between 119v to 126v.

   BrownBox was created to provide a safe range of optimized voltage reduction levels for tube amplifiers. Today, we 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.
