Genalex Gold Lion 12AU7 Tube
TUBE INFO: These tubes are Brand New in factory retail boxes from the New Sensor Corporation. They're another fine example of the reproduction tubes NSC is producing under the Genalex Gold Lion trademark. How do they sound? Summed up, they feature full, rich, liquid smooth tone that you would expect from a tube carrying this prestigious name.  Each of these tubes was checked out on a Vacuum Tube Characterizer from VTV which along with gain and shorts, also tests for NOISE and MICROPHONICS. We also go one step further by double-checking them on a Maxi-Preamp Tester to confirm the VTV's measurements.
