Yaqin Audio MS34B (Branded as Silk Audio MS38B)

Silk Audio SA38BT
Silk Audio is pleased to present the new Silk Audio SA38BT.  Manufactured by Yaqin from its MS34B, it is evolved from the previous Yaqin MC30L/MS30L that has been popular with many customers. 

 The 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 screwdriver, 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.

Other features include selectable Ultra-Linear and Triode modes and VU meters for each channel, all assessible on the front panel of the handsomely designed chassis.

Please note the pictures are for an identical stock Yaqin MS34B.  The actual item is branded Silk Audio SA38BT.
