A durable 8-pin octal tube socket designed for chassis mounting in tube guitar amplifiers, bass amplifiers, and other vacuum tube equipment.

This bottom-mount version features a black plastic body with an integrated metal saddle plate and solder terminals for traditional point-to-point or hand-wired amplifier construction. It is commonly used with octal power tubes and rectifier tubes and is an excellent choice for amplifier repairs, restorations, modifications, and custom builds.

The socket mounts from underneath the amplifier chassis and requires an approximately 1-1/8" chassis opening.
