    I bought these to try out, but am sticking with my 12AX7 for now. These are the exact same as the RCA made clear top tubes, but labelled for Conn organs. They're in great condition.

    According to the dealer I bought them from:

    They are tightly matched and balanced, test right in the typical NOS range, and have excellent pins and flashing...They are also free of noise and microphonics...

    Fully tested on a recently calibrated B&K Dynajet 606...Average for new ecc82/12au7's is 85-90 and a minimum good of 65...

    Tube 1 tests...88/87

    Tube 2 tests...89/91

    Shorts, Gas, Grid Emissions-None ​

    GREAT tubes at a really good price, [DEL]$16[/DEL] $12 shipped CONUS.
