Auction is for one (1 pcs) tube, ECC83 12AX7 Telefunken, diamond bottom, made in West Germany, in 60s. One is smooth plate version, another one is ribbed plate version.

These are real Telefunken diamond bottom ECC83, pullouts from Siemens Klangfilm amplifier. They are low noise and tested NOS and even stronger than NOS, so they have a lot of life left in them, in some well designed preamp, even decades. The same codes, fair printings.

They are tested with 250V on plates and -1.5V on grids:

Smooth plate one 1: 2.3 / 2.0 mA
Ribbed plate one 2: 2.6 / 2.9 mA

100% value for NOS tube is 2.15mA
