ECC83 12AX7 CV4004 Brimar, short grey plates

Description

Brimar ECC83/12AX7, looks new, tests new but may have seen very minor use. Call it burned-in…

These were taken from military spare test equipment that was just sitting around and was never really used. These tubes are absolutely clean, look unused and test accordingly with at least 100% of a new tube in terms of transconductance/gm and emission. Most test actually 100%+

All tubes are super balanced in terms of gm!

Small batch available! Out of the batch we would be able to build 2 matched pairs. Please request when ordering if needed.

You will not find a lot of vintage ECC83 in this condition out there!

On some tubes of our batch the code is hardly or no longer visible. We reserve the right to deliver either version but guarantee that these are genuine Brimar tubes, even if no code is visible anymore.

Tubes came in a bulk crate and will hence be supplied in a plain white box.

Each and every tube will carefully be tested before shipping to guarantee best performance.

We also do have other ECC83/12AX7 in stock from various manufacturers. Please ask…
