Welcome to the Phorum!
The 42-322 has an electrodynamic speaker that requires the radio to be operational and the field coil that provides the magnetic field for the speaker to be working. I noted in the article you mentioned the following advisory for using the method #2: "Important Note: Commenter J.W. Koebel brought to our attention that if you want to use the radio’s original speaker like we do in this project , the speaker needs to be a permanent magnet speaker."
So, you would need to put in a permanent magnet speaker to follow that course.
