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

[W5CPT]

I have an Icom IC-756 and an SB-200 and have no problems. I even can load them up on 12M and 17M with no fold back. Either I got lucky or my amp is just tolerant of my fumble finger tuning. I'd rather be lucky than good.

  I'll bet you are using an ICOM radio, there radios have a much too  sensitive 
  SWR foldback circuit.  I have owned almost a hundred SB-200's and  never had 
  such problem using Yeasu radios driving them.   Lou
