Centronic P4231-BA Photo Multiplier Tube! PMT! Vintage Tube! Working Pull!

Liquidating inventory from my fathers electron microscope service business. These photomultiplier tubes were removed from decommissioned SEMs all were removed from working equipment and tested prior to storage. They are guaranteed against DOA and sold with a 90 day warranty.

Please note we have multiple tubes in stock and the one pictured may not be the exact tube you receive. They may differ slightly in appearance but all properly function.
