-I put 125 volts (measured on the meeter) from the wall socket into the output transformer and measured 3.1 volts out.

-I then divided 125 by 3.1 to determine the turns ratio and got 40:1

-I then squared the turns ratio (40 time 40) to get an impedance ratio of 1600:1

-So...if I hook this transformer up to my 8 Ohm speaker the impedance that will be reflected to the primary will be the impedance ratio (1600) times the load (8 ohms) to get a primary of 12.8 K? And if I used 4 ohm speakers the primary would be 6.4K?

If someone could comment on wether I did this correctly I would be grateful. Thanks.
