Well there do not exist any circuit whose parts are not available anywhere.
Do you mean that "whose parts are available in your city" or something?
Then I am sorry but none of us know what parts are available to you.

Please be more specific with your questions so as to avoid confusion, mess ...... and waste minimum time to achieve your desired objective.
