Kit Build - NHM2035 Stereo Encoder

I got a piece of equipment in to fix and it requires a composite input. I don't have anything that has a composite output at the moment so I decided to buy a little kit that will take Left/Right audio in and output composite stereo with a 19KHZ pilot. Lets put it together, together. Where to buy the kit. http://electronics-diy.com/product_de...
