Here is one New in the beat up  box General Electric 6JS6B tube.I tested the tube on my Sencore Mighty Mite tube tester and it reads new at 100% with no shorts or grid-leakage. A lot of the delicate white lettering is worn off.. . Your tube tester readings may be different than my tester, but this tube tests new.  USPS 1st class shipping with tracking is $5. USPS 1st Class International Shipping is $17.  I have been selling tubes on Ebay since 1996 and i know how to pack tubes so that they will arrive safely. I usually ship on the next business day.
