If you live in the States, a good place to find parts for projects like this is in the All Electronics catalog (they're on the Web, too, but I don't remember the URL). They sell all sorts of discontinued/overstock/surplus stuff at very good prices, and I've never had a problem with quality. When the brick power supply for my 64 died, I designed a replacement heavy-duty linear PS with the All Electronics catalog and the back of an envelope, and put together a high-quality power supply for peanuts. BTW, years ago I came across a really simple, elegant formula for calculating what size filter caps you actually need for half- and full-wave rectified power supplies. If anyone is interested, I'll try to look it up. Also BTW: for a long time, All Electronics stocked new-in-the-box VIC-20 RF modulators (NTSC) for one or two dollars apiece... maybe they still have them. -- Brian _________________________________________________________________ Check out the new MSN 9 Dial-up — fast & reliable Internet access with prime features! http://join.msn.com/?pgmarket=en-us&page=dialup/home&ST=1 Message was sent through the cbm-hackers mailing list
