About the REN-70/70 Series 3 Signature

The REN-70/70 Series 3 Signature amplifier by Valve Amplification Company is a unique dual-mono tube power amplifier that uses Western Electric 300B filamentary triode output tubes, known for their natural linearity and superior sound quality. It delivers approximately 70 watts per channel in pure class A operation, providing the power and control needed for modern audiophile loudspeakers. Each 300B tube has its own independent heater power supply and cathode self-bias network, ensuring stable operation without user adjustment. The amplifier operates at around 450 VDC, which allows for superior output transformer design and speaker control. It features very low distortion (0.12% THD at 10 watts) and a wide frequency response extending from below 6 Hz to above 90 kHz. The REN-70/70 Series 3 is highly regarded for its accuracy, deep 3D soundstage, and rich midrange, making it one of the finest triode amplifiers available. It weighs about 78 lbs per channel and is hand-built with a focus on sound quality rather than just measurements. The The amplifier comes with a set of Shuguang 300B tubes and Electro-Harmonix 6SN7 tubes, power cables, and factory packaging for tubes. It is designed and built for audiophiles seeking a combination of purist tube sound and modern amplifier power and reliability.
