Crystal Radio Audio Amplifier. Here is a simple audio amplifier using a TL431 shunt regulator. The amplifier will provide room-filling volume from an ordinary crystal radio outfitted with a long-wire antenna and good ground. The circuitry is similar in complexity to a simple one-transistor radio but the performance is far superior.

LM386 Audio Amplifier Module The first time I heard something from the crystal radio, it was really exciting. But the volume is just too small to keep enjoying it. After a bit of Googling, I found a simple audio amplifier chip LM386, which …
Can I connect an amplifier to a Crystal Radio?

\$\begingroup\$ i think you get the most power out of the crystal radio when you match the impedance of the headphones with the output impedance of the audio output of the radio. i would have to think about it a bit, with tank-circuit, and i dunno exactly how the half-wave rectifier would affect the computation of output impedance, but i would bet it would have …
