This matched pair of GE 12AT7 / ECC81 dual triodes was tested on my Hickok 600A for shorts, gas and transconductance. There were no shorts or gas. Transconductance measured 2800/2800 micromhos for Tube One and 2800/3200 micromhos for Tube Two. (New 12AT7 typically test within 1.5 standard deviation of 3500 micromhos).

WE HAVE A VERY LARGE SELECTION OF VACUUM TUBES. PLEASE CALL OR TEXT US AT 202-372-6931 IF YOU HAVE QUESTIONS AND/DO NOT SEE WHAT YOU NEED.
