Why not spend under $2* and tell us? Somewhere I posted that you only need one Cree, just put it between the diode bridge and the rest of the power supply circuit, going to the first capacitor. You add a volt and a fraction drop that will be inconsequential. This is an old trick from years ago when Crees were hard to find and expensive. Second thought: you can put it anywhere in the power supply like after the final cap and before the wire going to power the circuit. It filters anywhere.
*Buy the Cree from Digi-Key, ask for the first class mail option. You will spend less than $2 and can bring information to the board.
