Matched Pair RCA 6AK5 Vacuum Tubes Steel Plates Secret Bankers It measured 50/46 where minimumThis perfectly matched pair of RCA steel plate 6AK5 tubes was tested on our Paul Hart calibrated TV7 U tester for shorts, gas and transconductance. There were no shorts or gas. Both tubes measured 25 where minimum (65%) is 22. These tubes have steel plates; top D getters and excellent flashing. I am playing them now in my Mini 2013 as I write and they sound excellent. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES. IF IT'S NOT LISTED, WE MAY HAVE IT.
