These 9-pin vacuum tube sockets are designed for top-mount and side-saddle chassis installations across classic audio amplifiers, vintage receivers, and specialized electronic equipment. The selection includes 9-pin Noval/miniature side-saddle sockets—ideal for standard 9-pin tubes like the 12AX7, 6BQ5/EL84, and 6CG7—as well as specialized 9-pin octal-style sockets. Offered in black molded compound, brown phenolic, and high-frequency ceramic with brass contacts, these sockets feature chassis-mounting ears for top surface attachment and integrated solder lugs for point-to-point wiring underneath. Available NOS and new stock.
