Описание к видео TRF AM MW radio with LED as a AM demodulator.

Medium Wave AM radio with old germanium transistors and yellow LED as a AM demodulator.
Circuit can work with any HF transistors PNP or NPN structure.
If use NPN transistors - need use correct battery polarity, electrolytic cap polarity and LED polarity.
Circuit use old telephone capsule ( TK-67-HT ) as a headphone.
For lower voltage (1,5...3V) battery can use germanium diode, silicon diode.
