No luck so far. I tried the LunarCorps at a bunch of different sound levels. Tomorrow I will put the logic analyzer on the Minstrel and see if I am getting audio to the input circuits.
Thanks for everyone's help. Hope to get this solved.

Re: Loading a program to my Minstrel 3
Thanks for the replies. Is there a known working .wav file that someone can point me to to test? Last night I pulled out my data cassette recorder.

Loading a program to my Minstrel 3
Hi, I cannot load a file to my Minstrel 3. I am playing them from my iPad. I verified that the audio cable is good by connecting a speaker to the end of the cable.

Cable for ZX Keyboard
I hope this is useful to others. Rather than building an adapter board as described here: https://www.zx81keyboardadventure.com/2019/12/all-new-zx81-minstrel-issue-3-kit.html I opted to just do it all in a cable, somewhat cleaner. http://i8008.net/ZX81/ZXKeyboardCable.jpg Schematic available in pdf ...
