Class-A Hybrid Stereo Poweramplifier

Elegant, timeless, clean technology, perfection for a power amplifier. Here, valves creating the typical sound that is amplified in the power section by the transistors. In addition, the voltage stabilisation works with a 6N10 valve and thereby provides a trouble-free 10W Class A operation. The secret tip.
