<VV> oily radios

[Frank DuVal]

Ahh, but the model T coil was an LC circuit and had a built in condenser 
in addition to the coil inside the wooden box.. See Skinned Knuckles 
magazine recently on how to overhaul these time capsules. The Corvair 
coil is only iron, wire and oil.

OK, some bakelite to seal the top...
