Looked into the suggestions by WA2ise and old_coot88, and all that looks OK. I was about to follow up on Reece's recommendation of getting the signal with a loose link from the good set, but I got carried away with trying to learn what I was doing. Then the Frequency Fairy appeared and promised to put a signal generator under my pillow next week. Before I can use that, however, I need to know how to assess or measure signal or output strength. Is this something I can hear, or am I measuring audio output from the voice coil, or what? In case it might be useful, I have a 1960s analog Micronta multimeter with an output jack.
I've posted specs, alignment instructions, etc. in the last 5 or 10 images in this album:
