ECC83 12AX7 CV4004 Brimar, short grey plates, gently used

Description

Brimar ECC83/12AX7, looks new but tests slightly used

These tubes 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 around 85% of a new tube in terms of transconductance/gm and emission.

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…
