    I want to connect my 8 ohm 1912 Marshall cab to my SV20c combo, whilst keeping the internal speaker (16 ohm) connected.

    How can I do this, please?

    It's Ok - I found my old thread on this, so all is clear!

    That's OK.
    Glad you found the info.
    I assume you found info on the 5-jack mismatch solution.
    Plug the 16 into a 2x8 jack and the 8 into a 2x4 jack.
    The two half loaded pairs of jacks add up to a full load.

    Yeah those 5 speaker outputs on some Marshalls is a little confusing at first. I recall some members looking for help on how to use these spk outputs, as far as getting the ohms right. But once you do understand how to use them, it makes sense.
