Summary edit

Description

A type 6П1П (English:6P1P) miniature 9-pin beam tetrode vacuum tube manufactured in the former Soviet Union circa 1980s.

The glass enclosure has been removed from the vacuum tube. View of the anode (the large gray cylindrical part with flat vertical surfaces on two sides) and the getter pan. The getter pan is the shallow cup-shaped part at the top. The getter is a powdered metal (Barium) that reacts strongly to oxygen. When the tube is sealed, the getter is fired (heated) to remove residual gas from the tube to achieve a higher vacuum than the pump could achieve alone.
