So could you provide the diagram?

Thanks Ernst.

I didn’t upload a schematic picture to my imageshack but the schematics for the bare bones unit, the BAS40 and WR3 can be found on Stephen McGreevy’s site. You’ll get the general idea.. It’s a JFET input circuit driving a simple audio amp. There is also a magnetic loop variant schematic which might be of some use for Tesla coil builders…

Stephen’s site: - Natural VLF Radio - Sounds of Space Weather - The Music of the Magnetosphere
The top schematic is what I worked with:
