That's just it. There IS no wire, nor any electrical connection of any kind. Maybe it's supposed to feed back through the B+ line, but I don't think so, or it would get to places it's not supposed to. Not a very good schematic here, but you can see it's a simple Hartley oscillator. It is actually difficult to make these NOT work.
