Matched Pair General Electric GE 6AU6 6AU6A Vacuum Tubes Geprueft RC2 RC-2 Plates: gray ladder plateThis matched pair of GE 6AU6A tubes was tested on our Paul Hart calibrated TV7 U tube tester for shorts, gas and transconductance. There were no shorts or gas. Tube One measured 67 while Tube Two measured 69 where minimum (65%) is 58. I have played them in my Musical Paradise 301 MK 3 with adapters (not included) as 6SJ7 substitutes and they sound excellent airy with excellent dynamics and signal bandwidth. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES.
