The Mistral-1 is a high-end monaural power amplifier that offers modern sonic characteristics and robust driving power. Based on the Cavatina series model line, Analog Design developed the Mistral, a single-ended monaural power amplifier with a pure A-Class 20 Watts output, which operates the 6C33C as an output tube. As a military triode, the 6C33C is the most preferred output tube for modern high-end tube amps. The high plate current (Ip) and low plate resistance (Rp) of the 6C33C Triode and their excellent performance and sound quality are already well known. It is not easy to actually find a high-end tube amp model that perfectly derives the original characteristics of the 6C33C. Analog Design has successfully completed the Mistral monaural power amplifier, which delivers the outstanding performance and driving power of the 6C33C.
