The power supply for some projects which electronics technicians & designers on this List may use may incorporate PCB-mounted transformers. I have just had some made and the photo and specifications are at http://kitsrus.com/bits.html#trans They are made in China but with Taiwanese material and Taiwanese product specifications. (Chinese material and specifications are cheaper but also lower quality. I do not recommend using them.) Minimum orders are 5000 pieces. For the one in the photo and the spec provided I paid $US0.295 each. So if anyone wants 5000 to their own specification, or just want to buy a couple of these get in touch.... regards, Peter Crowcroft DIY Electronics (HK) Ltd PO Box 88458, Sham Shui Po, Hong Kong Voice: 852-2720 0255 Fax: 852-2725 0610 Web: http://kitsrus.com Email: peter@kitsrus.com Number One in Electronic Kits Worldwide ------------------------------------------------------------------ -- http://www.piclist.com hint: The PICList is archived three different ways.
