Hi Don,
     Oh OK! That makes sense....the screw is at ground potential and
therefore less affected by a screwdriver adjustment.  I looked at the
schematic and got it all fiqured out.  Thanks so much for taking the
time to help out a fellow builder.  

See you on the air soon!

Dean,

OK, if there is any confusion, use your ohmmeter.
Measure the board to determine the lead of the component that is 
connected to ground - that is the ground side, and then with one 
ohmmeter lead on the adjustment screw, see which lead is connected to 
that adjustment screw. Connect the adjustment screw lead to the ground 
lead on the K2.

Note that this will not produce good results for the C27 trimmers.since 
both these trimmers are not connected to ground - that does require an 
insulated tool when adjusting either of those capacitors.
