The Tube Amp Doctor 7025 / E83CC Highgrade is the premium selection of the RT003 ECC83-Cz for V1 positions. This tube works exceptionally well in the V1 position of high gain amps, combo amps, and phono/audio-amps.

The Tube Amp Doctor 7025 / E83CC Highgrade is a miniature, high-mu twin triode with good gain, round deep bass, somewhat compressed mids and very smooth top end. Selected and recommended for guitar amps to smoothen up the tone or for HiFi to shape the body of sound more to “that” tube tone. Best for jazzy and thick clean as well as for vintage bass response. The TAD™ 7025 / E83CC Highgrade can replace any 7025, 12AX7WA, 12AX7WB, 12AX7LPS, 12AX7EH, ECC83 or E83CC.
