They talk of results with a 1K:8Ω Radio-Shack audio transformer: "Because I was using the phones in series, the better-performing units were actually presenting an impedance of 100 to 120Ω. When used with the Radio Shack transformer, the transformed impedance of the 120-Ω phones was about 2.8 kΩ, as compared to the 1 to 1.5-kΩ impedance presented by the …

The turns ratio relative to 16 ohms is sq.rt 7903 /16 = 22.2:1 For the 5 watt primary, the load impedance is 70 x 70 / 5 = 980 ohms. The ratio relative to 16 ohms is: sq rt 980 /16 = 7.82:1 Finally, the ratio for the connection you gave is 22.2 - 7.8 = 14.4:1 The partial primary impedance is: 14.4 squared x 16 = 3318 ohms. BTW:

1:2 turns ratio exhibited an impedance ratio of 1:4. Transformers always reflect impedances from one winding to another by the square of the their turns ratio or, expressed as a formula: Zp/Zs = (Np/Ns)2 where Zp is primary impedance, Zs is secondary impedance, and Np/Ns is turns ratio (which is the same as the voltage ratio).
