Inside the M7-HPA Liquid-Cooled Amplifier ...

Not a full production unit, but we're getting closer!

The warm glow of tubes- the M7-HPA is a hyrbid design that employs tubes in the input stage. In spite of its complexity the M7-HPA has only four parts (per phase) in the signal path and all of the logic and protection circuitry is analog. NO DIGITAL PROCESSING OR LOGIC OF ANY KIND!!!!
