    Can anyone explain to me why I would get a smaller DC reading across the load of my circuit than the predicted value even when the rectified peak voltage is almost the same as my predicted value? See revised thread

    There is no much information there. Has the load of your ciurcuit the same value as the input load of your probe or measurement device?

    Can you post your circuit? Click the "go advanced" button below, and attach a .jpg or .png image of it.

    Smaller is a relative term ... how much smaller? 12 to 11 is smaller ... but certainly within 10% of the desired (12).

    Post your circuit and describe or post the load.

    Their right, need input.

    A likely cause is if you're using a transformer it is loading down a bit, and coming out with slightly less AC under load.
