On the sch 89 (whatever it is - not too legible) denotes the speaker's voive coil, not the transformer's secondary from what I can see.
There was a thread where we discussed how to test a transformer.
One way of doing it is you could disconnect the primary and connect it to a Variac output, and bring the voltage up (10-20VAC) until you hear buzz from the speaker. It is a PM speaker so it should be easy.
