Ray:
 Is there a way to defeat the power line interlock other than pushing down on the switch assembly?  I am used (in other systems) to being able to pull on nominal push interlocks to defeat but that does not be an option here.

Couple things you got to have to work on the radio. First you will need a signal generator to inject 500 Kc into the output of the turret assembly. That will tell you that you're IF, Audio and all that sort of stuff is working. Also by default if the USB/LSB works your time base is good. Second is a scope that reads frequency, or if your smart you can determine frequency vs time, I am not that smart but have a scope that displays frequency on the screen and takes place of the frequency counter. This will help with determining what's going on with the six pack. Last and what's really useful is a second receiver to swap modules with. That makes everything easy! Think the other thing to look at is to confirm that all the mechanical alignment is correct. That can be a task on that radio but not impossible. Maybe plan a trip to someone who has a working receiver to see how the systems all fit together and try doing a couple things like injecting IF and the like at that time so you get a feel of what it's like and where your radio may be failing.  Things I have seen as issues is the mechanical alignment and muting interlock and the receiver protection on the RF input of the radio. Also dont overlook the stupid things like is your turret turning? Do the two tubes check good? And do you have the HV (B+) for the tubes?
Good luck.

Ray:
    Thanks for the posting;
As a CTM, I did not get training on R-1031, but Nick has provided me copies of the class notes.

I recently acquired a R-1051B, characterized as blows fuses. But that turned out to be mis-direction.   No fuses blow, but all I get out of the headphone jack is white noise , controllable by both AF and RF gain controls.  

So I am starting in "Troubleshooting-101", to see how many bad things I will find.
