Hi! I just got this board from a microwave power supply.I was wondering if I can use it and if I use it will improve something in my power supply like noise or "spark" or something this is just before the switch(if I installed it).I replaced the original 20amp fuse for a slow-blow fuse 3amp. thank you.
It is a filter for a 20 A load. That means it will not be very efficient for any chipamp, so don't use it.
