You are bidding on a Tung-Sol type 6SN7GT radio/audio tube, new old stock.  On my Amplitrex AT-1000 tester it tests strong at 102% of the specifications for a new tube for emission, Em, and 103% of the specifications for mutual conductance, Gm on one plate.  The other plate tests at 113% Em and 117% Gm.  It is a nice clean tube with no signs of use.  It should be great for your amplifier.   Shipping weight is 8 ounces. No shipping to China.  Please see my other auctions for more interesting radio and audio items, and tubes.
