[Elecraft] KPA100 Problem?

I am not an experienced builder, but having purchased a ready built K2, I decided that the experience of building a KPA100 would be good for me.  And everything has gone pretty well until I got to page 41 of the manual and conducted the tests.  Most (J3 lead, Q1 and Q2, and J2) are fine and the readings are as expected.  However, Q9 and D13  readings should be over 10K and I am getting 15Megs on my DMM, which is an older digital type.  Granted, 15M is greater than 10K.  Q9 (MOSFET) and D13 (Diode) appear OK and I have worked through the schematic, taking resistance checks along the way,  and everything appears OK.  I am thinking that it could be my DMM and any thoughts from the group would be appreciated.  Larry (G0IKE)
