[NJARC] Crystal Radio Parts

[Joe Giliberti]

Hey Everybody!

I am embarking on a delayed 8th grade science fair project by building a
crystal radio. I'm following the design for the "Improved Crystal Set" on
Al Klase's site. I've got myself a nice wooden box from an old galvanometer
and a 4 inch brass knob off of an old Variac for tuning. Most of the parts,
like the air cap I can find, but I'm having trouble finding a galena for
it. Any idea of a source?

Thanks!
Joe
