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. Depending on the amplifier, a Brownie user might discover that modern gear runs optimally at 116-118V. It’s impossible for an amplifier designed for 110V or 120V to sound or operate anywhere near the way it should at 129V.
Â
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.
Â
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.
Â
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.
