Two (2) fully tested NOS tubes, platinum matched pair of rare ECC83 12AX7 Siemens Halske made in famous Munich tube plant in 1960.
RARE - LONG Ribbed plates with one side hole, dual getter support version.
We have few 100 pcs boxes of these tubes and we had enough time last few months to carefully measure them on our Metrix and Tesla tube testers for plate current and Hickok for transconductance and to make platinum matched pairs with balanced triode sections. We have also tested them for noise and hum in my phono RIAA preamp.
They are real vintage NOS tubes, made in West Germany in 1960, carefully selected and matched from big batch. They are the same batch numbers engraved during sealing process.
