For your kind consideration is this Ruby 12AX7A preamp tube. Enjoy! Tested on our calibrated Hickok 533A and reads Good on the Good/Bad scale on both Normal and Life Test settings. Passes tests for shorts and gas. Mutual Conductance reads at 1350/1200 with 1250 being considered new. Overall this is a strong tube that reads at nearly new specs.
