Default Still superhet radios?

I recently took apart my AM/FM walkman and found no IF transformers in
it. Do these small radios still use superheterodyne type circuits with
a fixed IF frequency (455 kHz for AM, 10.7 MHz for FM)? I would love to
put my hands on a schematic but could not locate any.
