Matched Pair RCA 6AQ5 Vacuum Tubes Valves Silkscreened Base There is some marking inThis matched pair of RCA 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 42 while Tube Two measured 45 where minimum (65%) is 46 and 100% is 71. It took two adapters but was worth it as they sounded fine in my Mini Mite 2013, even though they test on the cusp. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES. IF IT'S NOT LISTED, WE MAY HAVE IT.
