Scott,
The PT-42 schematic is similar to the PT-96 and it shows a value of 500 ohms for the field.
If you use a PM speaker, you will need to also use the output transformer from the original speaker.
If your old speaker just needs reconed, many people recommend Hank Brazeal. Contact info can be found in this thread:
