Hello Henry.
The MB-V-A is a little unusual in that part of the balun winding
is in circuit all the time, except when you select the
"A Direct" switch.  That means that RF passes thru part of the balun
winding, even when you are tuning coax in the A or B positions.
I am not sure if this is related to your problem, but it has no
adverse effect that I have seen.

I prefer to leave the tuner in circuit to flatten the SWR, and reduce harmonics.
