selected preamp tube (RT010)
The TAD 7025 HIGHGRADE offers a warm, clean tonal character with a smooth transition into overdrive. It provides a stable response in sensitive gain stages, making it suitable for applications where low noise and controlled microphony are essential. In the first gain stage or as an input tube, it delivers a rounded, natural presentation that supports both clean articulation and creamy overdriven textures.

This model represents the highest-grade selection within TAD’s screening process, with only a small percentage of production meeting the strict noise and microphony requirements. It serves as a direct replacement for ECC83, 12AX7, 7025, and related variants, and is particularly well-suited for amplifiers that benefit from a low-noise tube in the V1 position. Compared with other HIGHGRADE types, it offers a smoother overall balance and lower inherent noise, making it also relevant for audio input stages and studio applications.

It features a linear response, controlled noise behaviour, stable operation, and Highgrade selection and matching by TAD in Germany.
