    Good little audio transformers, ideal for traditional transistor radio circuits etc. Knocked a star off appearance due to a couple of items having bent pins due to poor packaging. Managed to fix with a pair of long nose pliers.

    Despite the current global COVID situation I was surprised when the order came in less then 3 weeks. Thank you, I'm very satisfied.

    Wrong declared product. This is not 1300 to 8 ohm. Transformer has turn ratio about 5:1. Ideally, it would then be 25:1 impedance ratio, so in this case it would be 200:8 ohm transformer. But because of big losses in copper and core, primary side sees 400 ohm when secondary side is loaded with 8 ohm. Efficiency of the transformer loaded with 8 ohms is about 50% at 1kHz, mostly due to copper losses. Primary DC resistance is about 80 ohm and secondary is about 3 ohm. Core is EE type, with no I lements

    Decent product, true ratio for me is 80:3 which works for me but if you needed true 1300:8 then watch out. A couple have ended up not working but for the most part they are good.
