You mean like this one?

Or this one?

Ok! So I did not look! Relying on a 75 yr old, meds ridden memory!

Over 100V seem very possible to me. As I said the little AC supply starts with 85V The Focusrite probably will have meatier transformers. Actually I would say that is an encouraging result? Shows most of the circuit is intact and likely just the regulator that needs attention.

It has a separate Tr Trs input , that is fine . No voltage. So something I suppose.
