This matched pair of GE nickel plate 6AU6 tubes was tested on our Paul Hart-calibrated TV7/U for shorts, gas and transconductance. There were no shorts or gas.
Transconductance measured 52 for Tube One and 55 for Tube Two where minimum (65%) is 58.
These tubes have top, harp getters; nickel plates and excellent flashing.
Also, 7 12AH7s
I am playing them in my Musical Paradise MC-3 single-ended integrated amplifier (with adapters, not included) with Aimee Mann's seminal "Magnolia" album and they sound terrific. These tubes have great bass and sparkling highs and Mann's voice is warm and clear as a bell.
