I am intrigued by the idea of putting together a few cap replacement kits. However, I'm not the best at electronics, and could use someone to help with getting together a list of the parts needed, and possibly writing some directions. If anyone is interested in helping me, please contact me off-list at [EMAIL PROTECTED] .
