Tube Amp Doctor 7025 / E83CC REDBASE™ High Grade Preamp Tube
The best of the best from Tube Amp Doctor (TAD), this tube is designed for both warm clean tones and rich overdrive. It's voiced for extreme transparency with clear bass, detailed mids, and smooth highs.
These tubes also have the absolute lowest noise from microphonics. Only 2-5% of tubes are considered High Grade.
Ideal in Fender and Vox amps, these really shine where clarity is desired. TAD also recommends this tube to upgrade Marshall, Mesa Boogie, hifi, and headphone amplifiers. It’s an upgrade to any ECC83, E83CC, ECC803S, 12AX7, 5751, 7025, CV492, CV4004, and MESA® SPAX7-A.
With REDBASE, Tube Amp Doctor has refined everything about its tube selection process. Each REDBASE tube is made exclusively to their specs, then tested in Germany with an additional burn-in treatment and matching process to ensure flawless performance.
