The TAD 7025HG/1 is a high-quality preamp tube with a warm and clear character. In clean settings, this tube delivers a natural and detailed tone, while overload remains smooth and musical.

This HIGHGRADE version is the result of rigorous selection, with only a small percentage of the production output meeting the high noise and microphonic requirements. The tube is fully compatible with ECC83, 12AX7, 7025, and similar types.
