After waiting almost three weeks for the slow boat from China to bring my little 60 watt halogen transformers, it looks like neither one of them is working properly. At least i can not get 12vac out of them no matter what i do. I tried hooking them to my variac and bringing it up slowly. That got me about 0.8vac on each one. I then hooked them to the filaments of a 26 tube for a load, and measured the the voltage at the pins and got about 0.8 vac for both again. This is straight out of the box with no modifications yet. I did not have this trouble with the larger wattage units. Am I doing something wrong? |

I don't understand. You're connecting a 12V transformer to a 1.5V tube? |

Ok, let me try it with a resistor instead, or a tube with a 12v filament. |

So it doesn't matter which pair you hook up to? I did observe the polarity. |

Sounds like the dc transformer is the way to go then. Thanks. |
