Amprx Power Solutions BrownBox Brown

BrownBox by AmpRx – Voltage Controller for Tube Gear

• 120 Volt AC, 50/60 Hz, 5 Amp Voltage Attenuator supplies up to 540 Watts, designed for small or mid to larger sized amplifiers (i.e. Fender Deluxe/Bassman/Twin, Marshall 50w/100w, Vox AC30). Can also be used for parallel or dual amp rigs.
• Easy to read back-lit L.C.D. display enables real-time voltage and amperage monitoring – also useful for diagnostics
• Two adjustment modes to help to fine-tune your voltage
• Proprietary transformer design wound exclusively for use with tube amplifiers, an industry first
• Equal or attenuated voltage output and a 5 amp fuse with in-rush current protection ensures that you will never accidentally overload your amplifier
• Powder coated EMF neutral housing and tough road rugged construction
• Silent, cool operation

Input: 120VAC, 50/60 Hz; Standard IEC AC cable Output: Two AC Grounded Outlets, Adjustable Voltage Reduction Power Handling: 5 Amps at 120VAC, 50/60 Hz, up to 540 Watts The BrownBox features flexible voltage reduction options that let you bring the voltage coming into your amp down to an optimal level, resulting in significantly improved amplifier performance. 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 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. 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.
