Hmmm...I must be one of the lucky ones. I have a 130-140 foot long 
dipole, 25 feet off the ground, fed with ladder (window) line. I am 
using a stock Johnson KW Matchbox.

I can get a perfect match on all bands (including WARC bands) with the 
following two exceptions:

30 meters: I can only get the match down to ~ 2.4:1 -- but close enough 
that I don't worry about it.

40 meters: Even though I get a perfect 1:1 match, I can only run about 
500 watts; any more power than that exceeds the 15 kV breakdown of the 
ladder line and sets it on fire (don't ask me how I know). <grin>

Maybe if you try changing the length of your feed line to the tuner...???
