This is new old stock GE 6072 Triple Mica Black Plate Tube.  This 1950's version was the best version ever made.  It features triple mica construction which further limits microphonics.   

It was tested on a military TV7 DU tester  above 100% of bogey/new specification.   

This tube had been stored in damp warehouse and the box was eat up with mold. 
I normally sell these triple mica versions for $125 to $150.   
Since I don’t have the box, I am selling it at a discount.   This is last one I have at a discount.

$90 plus shipping to your location.   P.M. if interested.
