Offered is a nice pair of Telefunken 12AX7/ECC83 Twin Triode Tubes. The tubes are clean and in good condition. Each tests good on the Jackson Dynamic Tester with robust triode readings and no shorts or inter-element leakage.  The test readings are as follows:  115%/117% and 120%/122% where the tester good range goes from 70% to 130%. These tubes have smooth dark grey plates and flat halo style getters with all good silver flashing. One tube has mostly clear printed graphics with production code as follows: Bhp01, this tube has a diamond 2/2 on the bottom. The second tube has all worn off printed graphics. The construction within appears nearly identical-this tube may or may not have a bottom diamond-it is not readily visible. These tubes are suitable for your finest Hi Fi setup. Likely early or mid 1960's production. Pick up the tubes for your own gear, robust readings may or may not match those on your own tester.  Seldom offered in nice pairs like these.
