I have received my new output transformer (Hammond 125C). I thought I understood the wiring but now I'm not sure. Since my primary impedance is supposed to be 680 ohms I don't see anything in the table below how I would connect the secondary wires. For testing purposes I will be using a PM speaker measuring about 5.3 ohms and a resistor for replacement of the field coil. How do I hook up this transformer? I have included the specs for the K-6 speaker. Here is the link to the transformer. https://www.hammfg.com/electronics/trans.../125a-125e
