Today I will be hooking up a computer to an arcade monitor. This is my first time taking on a project like this. I have no experience with the inner workings of a real arcade game except for 2 that I have stripped for parts. An Arch Rival cabinet I took apart had a noise filter that went in between the isolation transformer and the monitor's power input.
Is this filter needed (or recommended) for all arcade monitors? I still have the one from arch Rivals, should I go ahead and use it?
