L and R channel/Red and White in system chain


I'm going crazy over this and I feel totally confused + angry. Anyone up to solving this puzzle?:

Turntable junction box: color coded white and red;
Phono preamp: engraved R(ight)(white terminal) and L(eft) (black terminal);
Rumble filter: no color coding; just L and R input and output terminals, both white;
Main integrated amp: no R or L but only Red and White inputs (CD player that's partner to the amp says Red is Right and White is Left channel)

I am so confused as to how to connect the cables it drives me nuts. I thought Red is always Right channel; but my phono preamp has Black marked as Left and White as Right.

The rumble filter has no color at all and only says R and L, but if my main amp Red/Right and White/Left that different from the phono preamp. The sound seems ok in either combo but it angers me that I have to play a guessing game with high end stereo equipment. Please advise.

First, remember that the electronics inside the boxes don't know or care what channel they are marked. They will do the job with equanimity. So, if the colored markings on the phono pre are inconsistent with the other components, simply ignore the colors and use the engraved R as right and L as left (or conversely, ignore the L and R markings and pretend that the black terminal is actually red. This would reverse the engraved markings; but as I say, the phono preamp doesn't care). The rumble filter (I assume KAB) only needs to have the connections consistent on the way in and out--so designate one side as red (R) and one side as white (L) and you are good to go. Finally, just to be sure you've maintained consistency throughout the connections, just listen to some familiar music--if the violin section in an orchestra is coming from the left, for instance, then you've conquered the mountain.
