Why is this step-up transformer stepping down the voltage? Some help would be appreciated.

Are you kidding!? Where do you measure the i/p voltage to the transformer! Before or after the unnecessary 10 ohms in the primary loop.

Measure the input voltage across the primary winding, not at the source. You’ll then see it does step it up. Remove the resistor and you’ll also get what you were expecting to see.

here another idea for better understanding, move the resistor and you can compare the voltages better http://everycircuit.com/circuit/6397857511505920

Thanks for your comments! Check it now, easier to vizualize the transformation ratio.

you can make use of the voltmeters, yes. This looks nice. But i can tell you to not use them cuz they are stupid for many reasons. Only in case you have to show a voltage not referenced to "ground" they might make sense. But even then they are flippy, means they change by "random" its polarity and they got lost as monitor in case you use the bode plot and they need plenty of worksheet space. All in all they are useless.

Ok, they look nice
