[Amps] MFJ tuner and SB-200 for input matching

[Tom LeBron]

 Hello all, first time posting but been reading for a while. This is an interesting question. My SB-200 seems to have the input that appears to be off. Every time I try to tune, I have to use the radios internal tuner to get an swr that's acceptable to get the drive just to get 500 watts out put on the linear. 
   Not to hijack the thread, but is there a way to check the inputs on the SB-200 with a MFJ tuner or Autek VA1 vector analyst. 
  Thanks Tom WZ9L
