Matched Pair Sylvania 6AQ5 Vacuum Tubes Valves Black Glass NOS-Testing December 22 2023 new in box US-made 6GV5This 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. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES. IF IT'S NOT LISTED, WE MAY HAVE IT. PLEASE ALSO SEE OUT ETSY SISTER SITE
