Almost sorta.
I had limited the other amp to well below that with external RC, and was
unable to get rid of the problem. Actually, I was unable to affect it
significantly.  The 6464 dosen't exhibit the rectification problem at all.
This is definitely a situation where the opamp is rectifying ambient RF
into noise on my signal.
