- ECC83MG(EU) / 12AX7(US) tube used in guitar amps.
- Reliable and low microphonics.
- New variation on the 12ax7 / ecc83.
- Mid gain.
- Medium long plate.
A (relatively speaking) recent design valve from JJ. They are a mid gain version of the ECC83s. Basically they lie somewhere in between the ECC83s and the 5751 in terms of gain. They have plenty of headroom and are often used in amps which need taming from too much gain. Has the usual JJ low noise and high reliability.
