Here’s a nice new old stock (NOS) combo – a ceramic chimney and matching socket setup for the popular 4CX250B, 4CX250R, 4CX150, and similar tubes (like the 8321).

This set is perfect for your amp build or restoration project. These parts are getting harder to find in good shape, and this one is unused – just shelf wear from storage.

✔️ Ceramic chimney helps direct airflow right where it needs to go
✔️ High-temp  socket – solid pins, clean contacts
✔️ Great fit for 4CX250B, 4CX250R, 4CX150, 8321, and similar
✔️ NOS – never used, just dusty from sitting on the shelf
✔️ Built to last – old-school quality you don’t see much anymore

Whether you’re building a grounded grid amplifier, repairing a vintage deck, or just stocking up for future projects, this is a solid piece of gear.
