    I want to pay 200$ for the price of item and 60$ for shipping cost(Total: 260$).
    I’ll wait for your answer.

    Hello Dragan!

    Nice collection! Congratulation!
    Good to see that you own these pretty NOS AD1s. Are these Hungarian ones? Tungsram was a tube factory here in Budapest. Now it’s GE and not manufacturing tubes at all 🙁 Do you have spare pair of AD1’s for sell or just for fun of your own? I plan to start collecting old Hungarian tubes for the posterity.
    Have a nice day!
    Kind regards,
    Andras Nemeth
