Does anyone know where to get these hollow tubes with internal threads on one end to take the two-piece threaded metal probe tip? I would like the probe tips to be included, unless you know of a source for those also. They need to be hollow so that I can insert the isolation resistor in series with the meter.

The resistor or wire lead is attached by soldering into a well on the 
metal probe which is not the way you described but it will work. I used 
a drill to cut through the nickel plating and make the soldering easier. 
The DCProbe used on the Heathkit VTVMs has to withstand 1500VDC which is 
proably beyond the rating of most current phone plugs. I recommend a 
military PL-55 here. (No, I don't have any spares.)
