Take a look under the chassis at V1, the first 1T4 tube socket. It's a 7-pin tube. The pins are numbered clockwise from the underside of the socket, starting with the first pin to the left of the wide space: that's number 1. On the schematic, see that the first grid G1 has the number 6 by it: that's pin 6. Count around to pin 6 and follow the wires from it and you'll see that one of them goes to the stationary (stator) plates of one of the gangs of the tuning capacitor C1. C4 is also associated with C1 and is probably the trimmer on the tuning capacitor. Also that same line continues to terminal 1 on L2, which I am guessing is a ferrite core.

Then look at pin 2, the plate, on that same 1T4 tube. It's wired to a two-coil transformer L5/L6 that sends the RF signal to V2, the 1R5. And so on.

What I like to do with a tricky schematic is print it out and then trace each wire one by one, and when located, mark it off on the paper with a highlighter. That way you know you didn't miss something and you get familiar with how that set is wired. Hope this helped. If you get lost somewhere check back in.
