Battery Powered Vacuum 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 Vacuum RIAA. Standard inverse RIAA network based on resistor or even better inductor as main part in the signal path, but NAT put Vacuum field medium instead. Phono stage contains 10 vacuum tubes in full zero feedback configuration.

Balanced Dual Mono Zero Feedback Vacuum Tube Line Stage

NAT Audio introduced tube balanced preamplifier called "Symmetrical New". New line stage is completely in dual mono topology also with zero feedback all triode vacuum tube design.

Reference Zero Feedback Hybrid Balanced Line Stage

Magnetic is a newest reference point line stage made by NAT standards – transformer coupled, class A with zero feedback circuit configuration. Special selected vacuum tube with fet is used - represent high technology in both industrial tube and solid state manufacturing.

Reference Absolute Zero Feedback Vacuum Tube Line Stage

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 6S31B-R output tube is used - represent high technology in vacuum tube manufacturing.

Single Ended Mono Block Power Amplifier

New version already improve quality of previous model by set power to 20W with special single gain topology. Single Ended Mono Block Power Amplifier Se1-GMI 83V has very short signal path without passive components. It means that this circuit contains no coupling capacitors & no inter-stage transformers.

Single Ended Mono Block Power Amplifier

NAT produced the most powerfull single ended (with Single tube) in the world called Magma New. It is called Magma, because the color of anode so real to vulkan's magma. Read soon much more about this unigue project.

Single Ended Mono Block Power Amplifier

Transmitter is a new reference point power amplifier made by NAT standards – pure class A, single – ended type and zero global feedback circuit configuration.

Single Ended Integrated Amplifier

For the first time NAT try to introduce real high-end component with a price region of entry level devices. The NAT “Single” is tube based integrated pure dual mono amplifier.

Plasma Effect AC Conditioner

Xenon is reference point power AC Conditioner made by NAT. Xenon give an opportunity to listen favorite music on two different filtration mode. In fact it represent two types of AC filtration in one unit. First mode is available immediately after plug in the power cord! It is also stand by mode that include high quality filtration, separated for digital and analog component.

High End Power Cord

Ac Coupler Black Signature is made to supply clean power to the high consumption analog components. Construction is based on shielding  hand winding special geometry technique with low capacitance and resistance design. Made from over 300pcs. of different material. Each cable takes few hours to complete. Dielectric: Air. Conductor: special OFC material. Shield: amophours material with addition of cooper.

Single Ended Mono Block Power Amplifier

Se2Se GM70 is the latest version of our over decade produced model.Pure direct heated triode amplifier is made by NAT standards – pure class A, parallel single – ended type with zero global feedback circuit configuration.

Single Ended Mono Block Power Amplifier


Microwave is a new power amplifier made by NAT standard with all tubes by military grade in pure class A, single – ended type, zero global feedback topology.

Main facts:

  • First high power metal-ceramic tube zero-feedback single-ended power amplifier globally, unique device
  • Most compact in the class (19"x19"x6.5")
  • Most efficiency in the class (280W of power consumption for 100W of pure tube single-ended class A)
