I see you are using a tuner. What was the SWR after the tuner. Having 1:1 
into the tuner does not count.
9913 should easily handle 10 KW. I can run 2.5 KW into a dummy load thru 
RG58 (perfect match).
A problem with 9913 is that  if it flexes or is bent often the center 
conductor will wallow out a large space
in the foam insulation and get way off center. Good old RG8 is best for HF 
and flexing feed line.
