All tubes are brand new, never used, old stock (NOS), produced in Eastern-Europe/Eurasia (like Russain Federation) before the 80's. They rested in a warehouse in Siberia for decades! They will see the sunlight for the first time when they'll get unpacked! Definitely not taken out from ancient or wrong machines!
