Audio-GD - HE1 Vacuum Valve Regenerative PSU Preamplifier
This tube preamplifier with Regenerative PSU design is unique! Its sound is pure not only because of the regenerative power supply but also due to its thought out design. The preamplifier is designed around vacuum valves, resistors and SOLEN film capacitors. That’s it! No concessions or compromises. Only the best is good enough.
