Check resistance between T37 and T39, should be 66.5K. T37 to T40 should be 75K. Now get some clip leads if you don't have them (cheap ar Radio Shack, very handy!) and shore out the capacitor leads of the 0.033uF. Then measure resistance T37 to ground; it should still be 75K.

No good? then maybe the 0.1uF is not connected. Resistance from the lead that goes to T36, to ground, should be 1.0Meg.

Well, in the previous post, I reported good resistance values  for T37 & T39.  T37 to T40 was 75K too.

I got the clip lead made and shorted the .033uF cap.  It took a long time for the VOM to stop, but it landed on 60KOhms for T27 & T37 to ground.

What does this imply?

Reheat the solder joints on all of these components. 

Paul is saying to measure from component leads so that the solder joint is verified.
