6AL5 Electron Tube Diode-Triode from Japan
The 6AL5 is a miniature dual diode-triode vacuum tube used in RF detection and FM discriminator circuits in vintage radios. It qualifies under HTS 8540.89.00.40 due to its thermionic diode and triode sections in a glass envelope vacuum tube design. Primarily used in restoration projects and amateur radio equipment.

Import Tips
• Provide vacuum tube filament voltage/current specs to distinguish from modern SMD components
• Include base pinout diagrams confirming octal or miniature 7-pin construction typical of thermionic tubes
• Declare quantities accurately as these are often imported in bulk for collectors and repair markets
