Magnetostat is a new reference point line stage made by NAT standards transformer coupled pure triode class A with absolute zero feedback circuit configuration.Military grade type 6N30P/6N6P output tube is used - represent high technology in vacuum tube manufacturing.Both tubes are also by N.O.S. (new old stock) grade and have high reliability.Construction of output tube 6N30P-DR is very robust also in mechanical domain means there is no high level of micro phonic effect for negative influence to the sound reproduction.Hand crafted wide-bandwidth output transformer (custom designed for NAT ) is used in this unit.Output transformer contain no less then 61 separate different material layers. Bandwidth is from 2.5Hz 160.000Hz. That is extremely good result for high direct current single ended transformer coupled operation mode. Total weight of transformer for one channel is approx. 8kg. Output has separate tap for single ended and balanced operation!
