A basic one transistor regen receiver uses an MPF102 JFET to give the regenerative gain. Also uses two transistors to amplify the audio to drive an earphone. https://www.circuitbasics.com/what-are-fm-receivers/

2017-06-13 Another Regen Receiver Built – Success!
The previous regenerative receivers I’ve built have been 27 MHz, but they have not been successful, they haven’t received a decent verifiable signal other than the very strong one I made with a dip meter. So this time I would build a regenerative receiver that is much lower frequency, and I chose 10.000 MHz because

2013-02-25 Regenerative Receiver Design
I received a Google Alert about this regenerative receiver schematic being posted to the RegenRX Yahoo Group (you may have to be logged on the view it). It’s quite complex for a regenerative receiver – the average regen set has just a few transistors. But its Achilles Heel is the front end. When I was
