VVA Venturi Vacuum Amplifier

Vacuum tube amplifiers used the first time in coast-to-coast telco circuits.

真空管放大器首次用于大西洋岸至太平洋岸的电信电路中。

A vacuum electron device made by the discharging currnt, that is, ignitron, has the features of resistance to high pressure, high power and fast current rise.

利用这放电现象制成的一种真空电子器件即引燃管,具有耐压高、率大、流上升速度快等特点。
