Here’s the quick rundown: The BrownBox is an adjustable AC power supply for your amp or tube gear that helps you run your equipment at the optimal voltage. Plug the BrownBox into the wall, adjust the voltage and then plug your gear into the BrownBox.
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. BrownBox users 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.
