Eimac SK-406 Electron Tube Chimney
The SK-406 Air-System chimney is used to direct cooling air from the socket across the glass envelope of the tube, past the plate seal and heat-radiating connector. It is made of sturdy, heat resistant Pyrex glass. The bottom edge is flat for a tight seal against the chassis while the top edge has been fired for smoothness.
