normal speaker impedance


A low, known AC voltage is applied to the secondary winding, and the
voltage is measured across the other. Be careful, because the voltage on
the primary winding will be high enough to shock you.

The voltage on the primary over the applied voltage gives you the
turns ratio. Square that number and you have the impedance ratio from
primary to secondary. Since the transformer is in a push-pull
application, the primary impedance is 'Plate to plate'.
