Hi Chuck,
I really haven't tried this, but what's wrong with the -w switch?  
Wouldn't that force wave files

I think this is defined as left and right channels, but if this isn't correct, please assume that it is throughout this post. Based on reading the sox man page, I think I can do the following, but I need someone to reassure me.

What I'm asking is if I record this tape as a wave file, can I then strip either the left or right channels from this recording?

Yes, it is for a purpose, and depending on what answers I get, I may or may not do what I'm planning, it really is a long story. Thanks for bearing with me, and for any help in advance.
