SANTOR Hybrid power amplifier

The Santor is a hybrid power amplifier with external power supply handcrafted by Claus Jäckle in Germany. It features a unique zero-feedback topology, a triode vacuum tube voltage gain stage, and a high-current MOSFET Class A output stage. 

Design and Technical Specifications

• Topology: Two-stage amplification with zero global or local negative feedback.

• Tube Complement: Uses 6922/E88CC tubes for input gain alongside ECC99 driver tubes.

• Output Stage: Six push-pull MOSFETs per channel biased heavily into Class A.

• Power Output: 50 WPC into 8 ohms; 100 WPC into 4 ohms (strappable to mono).
