Review on 🔊 5PCS Audio 1300 Transformer Transformador with Enhanced SEO by Maurice Branch

I did not buy these but others seem to find many broken windings hence 2 stars. What I would like to add is that transformer impedances are not the same as the DC resistance of the winding. They cannot be measured in the ohm range with the DVM. The transformer impedance is the impedance of the circuit at 1kHz for which this transformer is designed to operate with low losses. The impedance ratio is the square of the turns ratio or voltage ratio. Meanwhile, the copper wire may be different in different windings. Windings with fewer turns usually have heavier gauge wire, but the rule is not strictly enforced. So the DC resistance only tells you which winding has the higher impedance, not what the impedance is. Still, it's nice to hear what a DC resistance is. The seller usually doesn't bother to let us know.
