Hello Les
If you look at the schematic for that set I am sure it had a electromagnet speaker and some one replaced it with a PM speaker ,it looks like they took off the coil
from the electromagnet speaker and used it instead of resistor ,when ever you replace a electromagnet you should use a resistor in place of the coil ,you can do it this
way ,just use the coil instead of a resistor , but some coils are a lot harder to separate from the original speaker than yours,have a great day all the best Rick
