I received a TT 422 HF Amp a few weeks ago.  Everything seems to work 
well but I found one problem that maybe someone can help me.

When I go to 40 meters the SWR between the rig and the amp is about 2.2 
to 1 at 7.000 and down to 1.6 to 1 at 7300 KHZ.

All the other bands the SWR is flat.

The SWR is present even when I am on the dummy load.  40 meter antenna 
is flat.

My Question is - Should I just order a new board from TT?  It looks 
pretty easy.  But before I do, I just wanted to see if anyone else had the
problem and what was the solution.  and yes the 15/10 meter input board 
is installed.
