The first question is: how much will the students know in advance about
78 rpm curves? Having a selection of curves available is very useful for
someone who knows what's going on, and utterly bewildering for someone
who doesn't.

That said, the KAB VAP Mk2 might be a useful possibility, though its 
controls seem less than intuitive.
