    Two transformers are connected in parallel out of phase then I assume the net voltage obtainable is the sum of the output voltages?

    Two separate transformers primaries are connected out of phase, they still require correct phasing of the secondaries if summed, either through prior indication of the relevant winding start or by detection.
    If series connected, no harm can come of incorrect phasing, if identical windings in parallel, then incorrect phasing must be carried out or short circuit current is a result.

    The most accurate/practical way of paralleling transformer windings is normally to wind them bifilar on the same core.

    It's an old adage......

    "One picture is worth a thousand words."

    And not a schematic in sight yet.
