The Dynaco ST-70 Series 3 tube amplifier is 35 watts per channel and switchable between both 4 and 8 Ohm outputs, with Class-A push-pull stereo topography, that has long been characterized as a robust, reliable design of exceptional value.
The ST-70 Series 3 builds upon the proven design philosophies of the original David Hafler-designed Stereo 70, with contemporary design techniques resulting in exceptional performance improvements that meet the requirements of modern audiophiles.
Dynaco engineers have made extensive use of high-quality parts that were unavailable at the time of the original design including precision metal-film resistors, poly-composition capacitors, and miniaturized high-capacity power supply electrolytic capacitors. In addition, many of the newer parts are also built to tighter specifications than the originals.
