Quoted from docquest:Something I didn't think about is the power relay and projector I use fort his mod are designed for US 120VAC. For people outside US you would need some type of transformer to get the right voltage. I'm not sure if 50Hz vs 60Hz would make a difference or not.
Holy threat resurrection batman; but I thought worth adding for the archives. I have doc's light here in the UK - instead of plugging it into the machine I plug it into a step down transformer that then connects to the mains- It works beautifully.
