Cornet MM - Vacuum Tube Phono Preamp

The Cornet MM implements our 4th generation of this popular circuit, upgraded with a metal box and optional wood panels. The circuit topology features common cathode class-A gain stages with no feedback, passive equalization, and cathode follower output buffers with constant current sink loading. Power is supplied by a regulated wall-wart driving a boost converter (running at about 70kHz) generating the high voltage rail required for proper tube biasing.

This was light years ahead of my older NAD PP2." "I
