- Another 12AX7 variation from Sovtek.
- Fits 12AX7 / ECC83.
- Especially good in Marshall amps.
- Tried and tested design.
- Made in Russia.
Great vintage tone in these 12AX7WBs and with that bulletproof Sovtek reliability. They also have a really good noise floor. We believe these are the same as the Groove Tubes brand. Buy x3 + of any tubes and get a 5% discount auto applied.
