Single end 6CA7 — cast brass combined with polished cherry tree wood, point-to-point wiring, custom made output transformers. The output transformers are oversized and the amplifier operates eliminating negative feedback. The power of 8W with damping factor of 6, is more then enough for home use. Cherry wood used is naturally dried for over 10 years with polished finish. Unlike quickly dried trunk it is prevented of deviations, massive wood and brass construction contributes to nominal microphony of lamps, minimizing vibrations. Shielded transformers are screened which prevents any interference with the surrounding. The amplifier is designed for transmission of the refined details with highest definition.
