Transformer.

Transformers are typically either good or bad. You can measure the input side primary and the out put using a multimeter. Usually, if you have between 800 ohms and 1K ohms (on the high side), it's good to go. If it's lower, you can either replace it, get it rewound or use it till' it croaks on you and then replace it.

Hi Brian

thanks for that. The unit seems to run okay I was just a little concerned about the fire hazzard side of it all. Its old with old wiring running out of it that will need to be changed anyway. I might give it a go for a while to see if I can get life out of the old fella. I just don't want it to repay me by setting fire to the curtains and all the kids Christmas pressies.
