Yellow wires are for the speaker. The B+ dropping reaistor is marked on the board as 100k, but it really is 100 ohms and is also correct on the schematic. The board has several little solder bridges which have to be closed to allow it to work, presumably for measuring current to assist students to troubleshoot.

The speakers are so shallow, that there's no place for the cone to move.
The novelty radios have the same type speaker and the poor tone proves it.
BTW, can you post the schematic. It seems interesting. Schematics are the universal language.
