    I want to build an ac motor speed controller for elctric tool (for 230vac). I came across a circuit that is based on U208B ic (phase control) but all my effords to find the ic at local component suppliers here in Israel came up empty. perhaps someone knows a substitute to it and where it can be found? or if someone can suggest another circuit that I can use. I'm looking for one that can handle up to 1000W that will suit hand tools like drill, grinder and so (ac brush motors) and will maintain torqe.
    Thanks for your help.
