CONSTRUCTION circuit diagram looks wrong

The capacitor should be BEFORE the detector so that it forms a resonant (tank) circuit with the coil. The circuit diagram shows the capacitor after the detector: I'm sure this is wrong.

I think its wrong too! If its not fixed shortly, I will remove this misleading diagram--Light current 09:50, 18 July 2006 (UTC)[reply]

(original commenter) I've been looking at other crystal set designs on the midnightscience.com site and the classic 'Oat Box Radio' apparently uses this circuit with the phones across the capacitor (see http://www.midnightscience.com/project.html). Maybe I'm missing the point, perhaps the coil tunes through parasitic capacitance or something. But I still think it looks wrong, or at least misleading.
