5PCS B9A Ceramic 9Pin PCB Tube Sockets (GZC9C1/GZC9C1G) Overview A pack of five B9A 9pin ceramic PCB tube sockets designed for reliable mounting and electrical contact with a wide range of miniature vacuum tubes. Ceramic construction provides stable performance for temperature applications and longterm use. Key benefits Reliable electrical contact: Precision 9pin arrangement ensures secure connections with standard B9A tubes, reducing intermittent contacts and signal loss. Durable ceramic construction: temperature resistance and mechanical stability help maintain performance under soldering and operational heat. Easy PCB installation: Solderable pins match standard B9A PCB footprints for straightforward replacement or board assembly. Versatile compatibility: Works as a dropin socket for many common miniature tubes, minimizing the need to modify existing circuits. Compatibility Compatible with the following tube types and equivalents: 12AX7, 12AT7, 12AU7, ECC83, ECC82, E88CC, 6922, 6p1, 6p14, 6n1, 6N2 Model reference: GZC9C1 and GZC9C1G Specifications and attributes Type: B9A 9pin PCB tube socket Material: Ceramic body with metal contact pins Quantity: 5 pieces per pack Mounting: Throughhole PCB solder pins for standard B9A footprint Function: Provides mechanical support and electrical connection for miniature vacuum tubes How it solves common problems Replaces worn or damaged sockets that cause noise, channel dropouts, or poor contact. Offers a heatresistant solution for soldering and operation in tube amplifier and audio circuits. Simplifies retrofits and repairs by matching standard 9pin PCB layouts. Practical use scenarios 1. Guitar and hifi tube amplifier : degraded tube sockets to restore stable connections, reduce noise, and improve reliability during performance and recording. 2. DIY tube preamp or audio project: Install directly on your PCB to build compact, durable tubebased circuits using 9pin tubes. 3. Vintage radio or amplifier restoration: Use as a compatible replacement when refurbishing chassis and circuit boards that accept B9A tube types. Installation tips Verify PCB footprint matches B9A 9pin layout before soldering. Preheat soldering iron to appropriate temperature for ceramic sockets and use appropriate solder technique to avoid thermal stress. Inspect pin alignment during insertion to ensure flush mounting and consistent contact. What makes this product stand out Consistent fit for widely used 9pin miniature tubes. Ceramic body designed for improved thermal stability compared to plastic sockets. Pack of five sockets enables multiple repairs or projects without sourcing individual parts. This pack of B9A ceramic 9pin PCB tube sockets provides a practical, reliable option for servicing, building, or restoring tubebased audio and electronic equipment while maintaining compatibility with commonly used miniature tubes.
