Here are 5 new in the original boxes General Electric 6GH8A Tubes. The tubes were  made in the USA and have similar construction..I tested the tubes on my Sencore Mighty Mite tube tester and they all read new at 100% with no shorts or grid-leakage. USA USPS 1st class shipping is $4. International 1st class shipping is $15. I combine shipping for multiple purchases.
