Telefunken ECC83 / 12AX7 Smooth Plate
This is the legendary ECC83 / 12AX7 Telefunken smooth plate with diamond bottom. Having a very smooth response with articulated bass, this tube is one of the most desirable 12AX7 variants available. These are VERY rare and in short supply. These tubes are in original boxes. They have the <> in the base, say "Made in Germany" and have smooth plates. These are the real deal!
