ing down or powering at full input state at maximum volume. Such amplifiers are mostly large output transformer constant voltage output, there are a number of lines between the line transformer, if done incorrectly, it will in the open, shut down instantly generate high peak inverse voltage amplifier tube breakdown. This circuit can be adopted before the first input signal amplifiers amplifier work off, before stopping the first volume down, thereby protecting megaphone is not impaired.
