Transformer for 1978 European Memory Man

A customer just purchased one on Ebay, and now it needs to work in Canada. What kind of transformer does he need to replace the old one? (assuming that's what it needs)

Looks like 24V DC centre positive.
Specs say 100mA.

Lots to choose from

I figured that would be the answer considering the non existent research I have done.
