The ECC83 is a dual triode vacuum tube. It's identical to the USA version 12AX7. The identification system is the ONLY difference. The 12AX7 and the ECC83 are identical.
These are employed in many professional audio applications such as preamp products and in PA use, an ECC83 is often employed as a phase splitter as well as in the earlier stages of amplification before the push-pull arrangement in the final output stage.
We can supply matched pairs if required.
