I dream about you going to your market (like I go to a huge grocery store) and ask the salesman to help you look in his large garbage can for a BF494 transistor. The BF494 is old and is not made anymore.
I go to an electronic parts distributor store and see all the transistors hanging in rows in labelled plastic bags, or order online from Digikey or Newark. When I order online then the parts are delivered to me the next morning.
If you assembled the one-transistor FM tuner and it does not work then please post a photo of the circuit so we can see if your layout will work at the very high frequency of about 100MHz.
