Electro Harmonix 12AX7EH Matched Pair, NEW, Russian, Hickok Tested

This is a matched pair of Electro Harmonix 12AX7EH tubes.  These were made in Russia.

TESTING:  These were tested using a pair of Hickok 533A mutual conductance tube testers.  The mutual conductance (Gm) of both triodes is written on the side of each box. 

NEED A MATCHED QUAD?  Send me a message and I will see if I can put together a matched quad for you.  Glad to do it.

WHAT DOES "MATCHED" MEAN?  "Matched" seems to be open to interpretation, but here is how I define "matched".  The Gm of Triode 1 of the first tube is within 10% of the Gm of Triode 1 of the second tube.   The same holds true for Triode 2, the Gm of Triode 2 of both tubes must be within 10% of each other. 

PHOTOS: The tubes in the photos are a sample only.  Since I have multiple pairs of these tubes, the photos you see are probably not the ones actually in the photos.  The photos are only one pair out of many.

PRINT: The print on each tube is strongly and clearly marked Electro Harmonix, 12AX7EH, made in Russia, and the code 01 01.

SHIPPING:  Each tube will be in a standard tube box, and that will be inside a 32 ECT shipping box for safety.  It will be padded appropiately.  It's in my best interest for your tube to arrive in good condition, so I'll do my best to make sure that happens.

This tube ships quickly and safely from Mississippi.
