Matched Pair Sylvania 6AQ5 Vacuum Tubes Valves Black Glass NOS-Testing December 22 2023 tell you how the tubeThis matched pair of Sylvania black glass 6AQ5 output tubes was tested on our Paul Hart calibrated TV7 U for shorts, gas and transconductance. There were no shorts or gas. Tube One measured 62 while Tube Two measured 62 as well where minimum (65%) is 46. It took two adapters but was worth it as they sounded fine in my Mini 2013.
