The high-power amplifiers radio used in the broadcast room of cable radio towns in rural areas is easily damaged. The reasons are: The frequent use, non-service management, the radio is often shut down when it works in the maximum volume state or the radio is started in the whole input power. This kind of amplifiers radio is arge output transformer output. There are are many transformers in the circuit. The peak inverse voltage maybe breakdown amplifier tube when you turn on or turn off the machine. The peak inverse voltage is caused by improper operation. The circuit can turn off the signal before the amplifier start to work. And it can also turn down the volume before the machine is turned off. So that the amplifier can be protected from damage.
