Dumb question of the day but can a normal switching power supply be plugged straight into the wall (for testing purposes) or does it have go through cabinet wiring (filter, transformer, etc)?
My cabinet has a filter and giant transformer before going to a double wall outlet mounted into the cabinet, then the switcher psu and monitor plug separately into the outlet (ther is also a smaller iso transformer mounted on the monitor chassis).
Some of my pcb's make the large transformer hum even though the game works 100% and I would like to bypass the filter/large transformer if I could.
