Thank you Butch.  I purchased a used MFJ993B.  The original owner said he
opened up the tuner and connected something that was loose when he first got
it from MFJ.  Where have we heard this before??
He assured me that it was working well.  I believe him and I'll know before
long.

Thank you for responding too,

Kent, KK4FFF

Not much at all.  Just hook it up and have fune.  Hope you have a tuner to
tune a ballanced line.
