Generator CT Version 3 is a single-ended Class-A monoblock built around one military-grade ceramic power triode. NAT’s July 2025 revision introduced a linear-field output transformer, maintaining zero global feedback while improving the interface between the output valve and loudspeaker.

The ceramic valve uses a solid-copper anode and is operated conservatively relative to its maximum dissipation for reliability. Dedicated supply filtering, soft-start control and hand-wired signal paths support the amplifier’s combination of high power and triode simplicity.

Generator CT is offered in silver or black casework, with a machined aluminium chassis, protective top ventilation and high-current loudspeaker connections suited to a monoblock installation.
