AM FM Tuner .?
rdl:
The car audio manufacturers are making "disk-less" or "mechless" receiver units now. One of those might be adaptable, with the added benefit of playing FLAC or MP3 from SD cards. I'm thinking about getting one for my bedroom system since I can't seem to find a "disk-less" CD player. Though I may just settle for some kind of streaming solution.

There are plenty of "MP3 player" walkman style devices that do exactly the same thing, play music off internal flash or a micro SD card, many of these contain an FM tuner as well.
I've played with those little tiny direct conversion receiver modules, they actually work quite well provided you have a microcontroller to run them.

The OP perhaps wants to build a tuner the old fashioned way: ganged variable capacitors, IF transformers, and discrete components found in a classic superhet circuit.
But he has not replied yet, so we can’t know. Perhaps he was intimidated by all the digital radio suggestions.
james_s:
I do think it sounds fun to build an old fashioned analog tuner although it could be a fairly difficult project. Perhaps a compromise using a few more modern ICs would be worthwhile, I remember there being some analog "receiver on a chip" ICs that do most of the heavy lifting. Some simple AM/FM radios didn't have much inside.

Yes, these are hard to come by. ;)
