Model 20 speaker or model 70 ?
#5

Here is a drawing showing how a push-pull audio output transformer should be connected to your speaker.

A Hammond HX-125B (5 watt output), available from http://www.radiodaze.com should work well on your speaker. You will need a universal type push-pull output to match to the speaker voice coil, regardless of where you purchase one.
