Jim--
It sounds like you are just shooting in the dark and hoping for a hit. Are 
you measuring anything?
Remind me-- what is your antenna?

I understand least amount of inductance.  I can email a Power Point file of
what I have.
if any one is interested.  Just ignore my notes.  They just remind me what
I have done
so I do not do over again.

I am not getting multiple minimum SWR points.

If I move the external capacitance in
between the 2 external inductors I can run 500 watts with out an arc over.

Keeping the 100 pF external cap there and add another 100pF cap back at the
antenna
going to ground the cap in the MFJ-989 B starts arcing around 300 watts
again.

I am at a bit of a loss.  My MFJ-998RT auto tuner will be back from repairs
soon.  If I
do not do something with this situation I will FRY the thing again.
