A traditional IF amp is a fair bit of work, and you have to know where to look for the IF transformers. Whichever way you go will probably end up with 10.7MHz ceramic filters.

Basic amplifier subsystem ICs are getting harder to find - you may end up with a fully integrated FM radio chip and ignore the circuit sections you don't need.

But,how do I Identify the IF amplifier stage in the whole FM reciever circuit
