Gently pull the tube straight up from its socket. Avoid wiggling it side-to-side, which can damage the pins or socket.
4. Insert New Tube: Align the pins of the new ECC82/12AU7 vacuum tube with the holes in the socket. Gently push the tube straight down until it is firmly seated. Do not force it.
5. Поново саставите: If you removed a cover, reattach it securely.
