About the Valhalla

The Valhalla Integrated Amp by Don Sachs is a 30 watt per channel tube amplifier that actually produces about 33 watts per channel with both channels driven down to 20 Hz. It uses three 6SN7 type tubes in the preamp stage and can operate with various output tubes including 6L6, EL34, KT77, and KT66 variants. The amplifier features high-quality components such as stainless steel epoxy potted transformers optimized for 6L6 tubes, VCap ODAM capacitors in the signal path, and a 64-step remote Khozmo attenuator with relay input switching. It is designed for use with efficient speakers rated 90 dB or higher and is noted for its quiet operation and holographic sound quality. Production is handled by a collaborator in Salt Lake City, with lead times of 8-12 weeks due to custom transformer orders. The amp comes with Russian 6P3S-E tubes and Shuguang WE6SN7 tubes installed. It is praised for its ability to drive tube-friendly speakers with ease and delivers a sound that is neutral and transparent, allowing the music to come through without coloration.
