のソケツト。[Claims for Utility Model Registration] A socket for a vacuum tube having an annular terminal that is attached to and detached from one end of a control grid electrode, and a support part that is provided at a predetermined distance on the outer periphery of the terminal and supports the screen grid electrode. A film made of an insulating material is wound circumferentially around the outer periphery of the terminal, and the film is provided between the terminal and the screen grid electrode, and one end is connected to the outer periphery of the terminal via the film. a contact finger held in an electrically insulated state and having a contact formed at its other end; a contact finger provided between the terminal and the contact finger, the contact of the contact with the screen grid electrode; a contact driving means for controlling non-contact, so that the resonant frequency between the control grid and the screen grid of the vacuum tube can be changed depending on whether or not the contact is brought into contact with the screen grid electrode. A vacuum tube socket characterized by:
