| Abstract: | The final electron tube power -amplifier is the chief part of TV transmitter, 90 percent maintenance cost of TV transmitter is used for service of the electron tube. The quality of signal is closely related to the state of the final power amplifier. Keeping the electron tube amplifier in a good State can reduce the maintenance costs,prolong TV transmitter lifetime, promote the quality of the screen,at the same time,it can also secure the safety of the broadcasting. It is essential that we should use and maintain this instrument scientifically. |
