The Yaqin MS-90B puts out up to 55 watts in ultra linear mode and 28 watts per channel in triode mode.  In triode mode the output tubes see the speaker load and the rise and fall of impedance in the speaker have a more significant effect on sound. Ultralinear is cleaner and more detailed and obviously more powerful and less effected by the speakers rise and fall of impedance thanks to the tap.

This is a major evolution from the previous MC-100B that has been popular with many customers. Here are some of the major improvements:
The circuit design has been revamped from the popular MC-100B. It retains the dual mono design, two independent amplifiers sharing one chassis and one power switch. It has been given premium capacitors and other audiophile components. The sound is now warmer but yet more resolving.

A major feature addition is the onboard Bluetooth 4.0 receiver. Now you can stream music directly from your mobile phone or tablet to the amplifier set to BT channel, making it a snap to enjoy any streaming service or your stored music.
Yet another key improvement is the addition of a bias meter, making bias adjustments very easy. One just needs to push a button for the tube to be checked and the meter will display if the bias is in an acceptable band. Using the included screw driver, one can easier adjust the needle to the middle and voila, you are done! One no longer needs to use a multi-meter and access the test points to adjust bias but that option remains.

To befit this new model, the factory has sourced Russian driver tubes 6H8C and Electro Harmonix KT88-EH tubes for a limited time. One does not need to worry about tube upgrades – it has been done!

Other features that have been retained from MC-100B include selectable Ultra-Linear and Triode modes and a dedicated power amp mode, lowering its input sensitivity to be driven by a preamp and a full function remote
