Matched Pair General Electric GE 6005 6AQ5 Black Plate Vacuum Tubes Black Plate Nonal Please see pictureThis matched pair of GE black plate 6005 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 59 while Tube Two measured 64 where minimum (65%) is 46 and 100% is 71. These tubes have stout, shiny, ribbed black plates and horseshoe getters. It took two adapters but was worth it as they sounded fine in my Mini 2013. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES.
