NAT MCX - MC step-up stage

Vacuum I.N.

Full Battery Powered Vacuum Tube MM Phono Stage

Our flagship phono stage!

NAT introduce NEW TECHNOLOGY IN PHONO REPRODUCTION: VACUUM BASED INVERSE NETWORK!

NAT set a new standard in phono stage state-of-the art product by new approach-vacuum based inverse network realised in model Vacuum I.N. . Standard inverse network is based on RC or even better LCR type as main part of the signal path. NAT put vacuum field medium instead. Vacuum I.N is based on 14 vacuum tubes in full absolute zero feedback configuration to form uncompromised MM phono stage!

Signature Phono

Vacuum based inverse network (Vacuum RIAA by NAT) Tube Phono Stage

NAT set a new standard in Phono state-of-the art product by new approach - Vacuum based Inverse RIAA network in model Signature Phono New - Vacuum RIAA. Standard inverse RIAA network is based on resitor or even better inductor as main part in the signal path! NAT use vacuum field medium instead. Signature Phono stage contains 10 vacuum triode tubes in full zero feedback configuration.

Magneto

Magneto - Single Stage Single Ended Hybrid Mono Block Power Amplifier

Magneto is an unique mono power (100W) hybrid amplifier made by NAT, based on scientific grade Single gold plated FET and Single nuvistor triode tube that operate in pure class A, true single-ended mode.

Symmetric

Reference Zero Feedback Balanced Line Stage

After over then fifteen years in production NAT replaced Symmetrical with new Symmetric line stage - as a new modern looking hybrid type only balanced operation unit!

Symmetric is a newest reference pure balanced line stage made by NAT standard - transformer coupled, class A with zero feedback circuit configuration. Special selected RF linear FET with vacuum tube is used!
