If you have only two backplates, the arrangement is:
Generally, older instruments have two backplates, but some newer ones are custom ordered in this traditional fashion.
The preamp card with the trimpots is actually identical in both instances. In the three backplate example, the card is rotated 180 degrees so the ribbon cable can feed through properly. This also means that the cards are compatible between new and old models (unless they've been upgraded/calibrated, then they are specific to a given instrument).
