      I’m glad that everything is ok and that you received these sensitive tubes in excellent condition. Would you be so kind to tell in which amplifier you use them and how do they sound?

    Hi, I Need a pair of 813s with a square/rectangular shiny plate right below the bottom ceramic support (as opposed to a large round shiny plate that some have)

    No rattles. Very smooth and dark main plate surface. Thick main plate construction, as opposed to thin plate as some have.
    Kindly send me photos and prices

    Kind regards Andrew
