tube 2SC5200+2SA1943 HIFI Audio Amplifier Board
Features:
1. The noise of the switch is small and will not have too much impact on the speaker. It is recommended to add a horn protection circuit. The horn protection circuit can not only eliminate the impact noise of the power amplifier switch machine, but also avoid the output DC burning the horn when the power amplifier is damaged.
2. The bottom noise is small. Zero floating small, do not need to do any debugging after installation, the output zero drift voltage will generally not exceed 50mv, and is relatively stable.
3. Free debugging. As long as the connection is correct, no one is wrong, basically it is a success, no need to do any debugging, beginners also have a very high success rate.
