rectifier placement

[mnhiphop101]

so i pulled the rectifiers from an amp im working on and i forgot to make a note of which ones go where. how do i determine where they go

Are they doublers or center tapped positive and negative?

2 + - + and 2 - + -
its a 5 channel amp. 2 are for the a/b side and 2 are for the class d side

1/3 of the rail cap terminals (positive and negative) will be directly connected. Ignore those terminals. Connect the rectifiers with the positive center terminal to the positive terminals of the rail caps. Negative rectifier to the negative rail cap terminals.
