Features:

User-selected amplifier modes, UT (Ultra linear) mode provides greater output power and TR (Triode) mode does smooth and rich sound.

User-selected pure post-stage and integrated modes;

Utilizes the audiophile capacitors and high quality metal precision resistors dedicated for audio frequency;

Output transformers manufactured with Japanese silicon steel sheet and oxygen-free enameled copper and high quality lacquer, which offer a wide dynamic range at full rated output;

Independent power supply for each channel.

Applies special potentiometer as volume controller with low noise, and durable;

Beautiful aluminum and steel heavy duty chassis, panel and bezels;

Provides user adjustable bias, test points and tool to refine bias of the output tubes.

YaQin MC-100B can use like a pure power tube amplifier or also an integrated tube amplifier
