About the Seven Ultimate Line Stage
The Tron Seven Ultimate Line Stage is a high-end, UK-built, valve-based stereo line preamplifier from GT Audio/Tron. Available information identifies the Ultimate as an upgraded version of the Tron Seven line stage, using premium silver internal wiring and a carefully selected, hand-built circuit. The standard Seven line stage is reported to use two Philips-branded 5687 valves and provides approximately 14 dB of gain. It has five line-level RCA inputs and one RCA stereo output, with a gain control, mono/stereo switching, and mute function. The Ultimate-specific published documentation is limited, and a complete manufacturer datasheet for electrical performance was not located; therefore, values not explicitly documented are marked as unspecified rather than inferred.
