7025WBHG TAD selected preamp tube 7025WB high grade (RT093-HG)

TAD 7025-WB Highgrade Premium Selected is a low noise, super low microphonic selected version of the 12AX7 that meets all specifications required for the tube to be designated 7025 and SPAX7?

The TAD 7025WB Highgrade is tested and meticulously selected for the lowest noise and microphonics for use in the critical first preamp stages of High-Gain guitar amplifiers where noise and microphonics could be an issue.It has a balanced tone with a little emphasis on the upper mid-range that gives a nice string attack and clarity to the sound while retaining a strong and defined bottom end. It will also do equally well in vintage guitar amplifiers. If used in sensitive phono preamps the tube adds freshness to the signal without being harsh or spiky.

The TAD 7025 Highgrade can replace any ECC83, E83CC, ECC803S, 12AX7, 12AX7A, 12AX7M, SPAX7?, 12AX7WA/WB/WC/LPS/EH, 5751, 7025, CV492 and CV4004.
