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.\u003c\/p\u003e\r\n\r\n\u003cp\u003eWhile 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.\u003c\/p\u003e\r\n\r\n\u003cp\u003eAmpRx 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.\u003c\/p\u003e\r\n\r\n\u003cp\u003eWhen 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.
