Ten(10) tubes works in perfect simmetry means five(5) per each channel.
Power supply combine vacuum tube rectification and double regulated stabilization realized with stabilotron tubes (plasma effect) and the last generation of solid state. Plasma power supply has very low and constant output impedance through a very wide frequency response.
Sound quality is totally independent against power supply instability, because all stages in preamplifier contain stabilisation.
Plasma Dual Mono Line Stage has superior sound characteristics.
