STAX SRM-700T Vacuum Tube Driver Unit

Ex-Demonstration, ex-display SRM 700T, great condition, sold with all original accessories.

"6SN7" GT tube has been adopted in the second stage of the vacuum tube system, while custom-made low-noise dual FET is employed in the first stage. The vacuum tube 6SN7 which has become the original form of 6FQ7 realizes simple and powerful performance. The hybrid type driver has adopted the high-quality non-inductive winding resistor from VISHAY Co. as a load resistance. The clear and high slew-rate vacuum tube sound has been improved further to polish up warm and spacious reproduction.
