100W 2SC5200+2SA1943 Audio Amp Board HiFi Mono Channel Post-Stage Amplifier Features: 1.The noise of the switch is very small and will not have too much impact on the horn It is still recommended to add a speaker protection circuit The speaker protection circuit can not only eliminate the impact noise of the amplifier switch It can also avoid the DC output from the amplifier from burning the speaker when it is damaged 2.The bottom noise is very small,even if the ear is close to the speaker,you can hardly hear the noise 3.Small zero point drift,no need to do any debugging after installation The output zero point drift voltage is generally not more than 50mv,and more stable 4.Using classic circuit,stable and reliable work,some misoperation in production will not necessarily damage the components With a certain degree of durability and high production success rate. 5.Free debugging. As long as the installation is correct and there is no human error It is basically a one-time success.There is no need to do any debugging.Even beginners have a high success rate Specifications: Operating voltage:±10V to ±45V(recommended voltage(+35V)-0-(-35V)) Rated output power:100W*1(4 ohms ±35V) Maximum output power:150W*1(4 Ohm ±45V)Very hot,not recommended Board size:80mm*50mm,about 35mm high after welding Spacing between input and output brackets:5.08mm Hole spacing between two tubes:47mm Power tubes on the board:2SC5200+2SA1943 Package includes: 1*Power amplifier board Note: Only the products in the above package are included Specifications are measured by manual testing,for reference only Please refer to the actual prevail,thank you
