Nat Audio Generator Push pull mono block tube amplifier (170 w) [Expired]
NAT proudly introduced Generator reference high power push-pull amplifier on the base of 811 pure direct-heated triode output tube, yet zero feedback design.
With power of over 170W there is capability for driving any loudspeakers both dynamic or electrostatic type.
Hand crafted symmetric wideband output transformer (custom designed for NAT) is used in this mono block. Output transformer contain no less then 63 separate layers per each output tube sum to 126 in total. Even power transformer of 700W contain 10 separate sections to supply each of amplifiers stage.
Special care has been taken in designing all high voltage regulators including for the output tubes.
The Generator is using zero global negative feedback primary to equalize characteristics for all type of loudspeakers (to have similar characteristics on dynamic and electrostatic loudspeaker as well).
Driver stage employ special quality military grade 6N1P-EV, 6N2P-EV & 6N6P tubes all with 10 000 hours of operational life time.
Audio circuit is absolutely balanced although at the same level of sound quality the single ended input option is available too.
The Generator is such a type of power amplifier that could be simple driven directly from the source (CD, SACD...).
