Competent in tubes!  audiotubes_de A few notes 1. I don?t measure GM. Ia is corresponding to GM 2. Most tubes are older than 50 years and have been "sleeping" for many decades Give them at least 3 days BURN IN 3. My tested results are based on my testers (and verified with many other tubes)   bid is for 1   tested  E83CC 12AX7  siemens Valvo tube Tube is labeled valvo, but with original Siemens Munich factory code tested with ~~150%  emission  These are genuine professionel ECC803s tubes for highest demands.  The code is completely different to the consumer tubes My testing equipment
