    Pretty standard fare, and exactly what I wanted and expected.. Small, potted, high voltage, step-up transformers. Quality seems fair to good, especially considering the price point. I haven't tested the input current yet, but my tests were done at 6VDC on an HP 6281A, in open air I got about a 15mm spark. The blue tape in the picture is mine. These have no markings whatsoever, and I didn't want to carve on the case. I don't know how thin the case can get before stray voltage becomes a concern. I lack the equipment to test the output voltage and current. While I doubt the 1MV, the spark is thick and healthy with a nice crack. I'll be interested to see what kind of duty cycle I can get out of them if I can keep them cool. A note on any transformer, running a transformer without any load will destroy it. When I got beyond spark distance the transformer hit a high note like a castrato. Keep the leads in spark distance or keep a load on it, although I'm not sure what kind of load could handle this power. Now I'm off to scare the girlfriend.

    El Inverter de bobina de ignición de pulso llegó en excelentes condiciones mucho antes de lo esperado. Es un producto muy bueno y la cooperación como siempre muy buena.
