Matched Pair RCA 6AK5 Vacuum Tubes Steel Plates Secret Bankers

Matched Pair RCA 6AK5 Vacuum Tubes Steel Plates Secret BankersThis 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.
