Single Ended Mono Block Power Amplifier

After a several years in production NAT revised (from November '19) a real high-end amplifier-Transmitter HPS (Hybrid Power Supply).

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

Transmitter HPS gives an opportunity to listening the sound on two different mode - high power setting to 80W or low power to moderate 40W, both of pure direct heated triode type. With power of 80W in single – ended configuration there is a capability to drive wide variety type of  loudspeaker.

Philips (or equivalent) QB5/1750 type as output device represent high technology in vacuum tube manufacturing. Potential of output tube reach 565W of heat dissipation! Transmitter HPS used only 40% of max. dissipation that significantly decrease working temperature point for further reliability improvement. Construction of output tube is very robust in mechanical domain resultated in microphonics-free sound reproduction. Special designed pure non-magnetic pipe type cover cage additionally improved negative vibration feedback effect from the environment, correlate to further increase of micro detail in sound reproduction. For the audiophiles with sensitive loudspeaker Transmitter HPS offer low mode option to lower the output power to 40W that further decreased power consumption of output tube - resulting to much lower heat dissipation.

Input and driver tubes (6N6P) are made by military standard, indicated as N.O.S. (new old stock)  grade of the highest quality.

Hand coiled wide-bandwidth output transformer (custom designed for NAT ) is used in Transmitter HPS. Output transformer is constructed with no less then 52 separated wire layers. Bandwidth reach 8Hz – 110.000Hz as exceptional good flatness for single - ended zero global feedback amplifier. Output speakers connectors are realized in laboratory grade style. NOTE: Transmitter HPS may drive speakers from 4 ohms to over 16 ohms. Zero global feedback concept is the best solution for purity of sound reproduction without negative influence from wide variety of speaker impedance.
