Matched Pair Tung-Sol 6AQ5 Vacuum Tubes Black Glass NOS-Testing Jerry Murad's EIA Factory Codes: RCA liveryThis matched pair of Tung Sol 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 68 while Tube Two measured 72 where minimum (65%) is 46 and 100% is 71. 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
