A transistor, a ECH81 or a SA612 will do it simply.
I have one that uses a ceramic resonator in the 400KHz region and a loop coupled well to Ever Ready Personal B at twice the frequency, which is as about the most deaf AM radio I have apart from the near identical Marconi and the slightly different MW/LW Marconi replacement model.

One transistor and resonator (or crystal). You can use fundamental or a harmonic. Use a tuned loop on collector.
