I haven't done that thus far. I may dig one out and take a look. But I
thought maybe someone else may have seen similar behavior.

Without having a look at the schematic and hazarding a guess I would say may
one of the diodes in the swr circuit is in trouble.
Are you using an external meter to monitor the SWR when the Turbo Tuner is
running the antenna?
