SP-331MK

Hybrid Class-A Stereo Power Amplifier

Elegant, timeless, clean technology, perfection for an end stage. Here valves create the typical sound that is amplified in the power area by the transistors. In addition, the new voltage stabilisation works with a 12 AU7 valve and thereby provides a trouble-free 10W in Class A operation. The secret tip.
