Yes, I, too, back before I had things clarified in my feeble, tiny mind by
Mariss, the genius guru! He pointed out that the power-supply to a
chopper-drive need only deliver WATTS, the current "coming" from the chopping and
capacitors. Yes, a poor way to explain it, but, well... Summaus jus' be dummies!
Sorry!

So, your motors add-up to 38.4 watts, and the transformer in question is good
for 100 W. MORE than enough! Use a good 5-amp bridge-rect (four 1N5002
would do!) and, say, 5000 uF of filter-caps.
