[Elecraft] receive sensetivity down about six S units with amp in place.

Don,

If it is down when the power is set to either low or high, then it is 
most likely the Low Pass Filters in the KPA100.  Is there any difference 
between the bands?, or is it constant across all bands?.  It is also 
possible that relays K1 and K2 are at fault.
If it happens only at high power settings, then the problem is most 
likely in the T/R switch area.
