ゲルマラジオを作りたいのに古いダイオードがもう手に入らないんだけどどうしたらいい？

I've made several germanium diodes and battery-free radios, but in the end, you can't get any sound without germanium diodes. However, germanium diodes have recently been discontinued and are difficult to obtain. So I've been thinking about whether I can make a germanium radio using parts that are still available. I'm trying to see if I can get a radio to work using several diodes. The results were different for the so-called germanium radio, which is a battery-free radio for AM use, and the battery-free radio for FM use.
