Introduction:
1. The 3CX20000A7 electron tube is a cermet coaxial structure, a direct-heated thorium-tungsten cathode, and a forced air-cooled triode with a high amplification factor. Maximum operating frequency 110MHz, maximum grid power dissipation 500W
2. Mainly used for zero-bias class B radio frequency amplifiers or class C power amplifiers and oscillators. The attractive thing is that the tube can obtain 20 times power gain when the gate is grounded.
3. It can be used interchangeably with the 3CX20000A7 tube produced in the United States
