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
