The horn speaker is 1275 ohms. Do I need a special amp?

If you have a strong local station it's possible to have a crystal radio with an amp that doesn't need a battery or AC supply. Some crystal radio guys build 2 radios.... One harvests a few volts of power from the local high power station to power an amp or regenerative stage and the other tunes the weaker stations for the gain stage.
