Beschreibung
Zusammenfassung:	An analog amplification vacuum tube of the present invention suppresses influences of filament vibration on amplification characteristics. The analog amplification vacuum tube of the present invention is provided with a filament, an anode, a grid and a vibration-proof part. The filament is tensioned linearly and emits thermalelectrons. The anode is disposed parallel to the filament. The grid is disposed between the filament and the anode so as to face the anode. The vibration-proof part includes a thin film usable in a vacuum environment and the thin film comes into contact with part of the filament.
