 Yeah, they call them "modules" . Modules are supposed to make servicing easier. It's just not the case with the R392.You have disassemble the whole radio to get them out!No wonder your brain hurt.Mine did too after pulling the oscillator "module". 

Did what I had to do and put it back together, I decided that pulling the others "just to check them" would be more work that it was worth.

 See the photo attached. I had an audio section in my R-392 that needed 
work. (The whole thing needed work!)  I was getting leaky capacitor 
sounds in the audio, so I took the modules out of the R-392 and was very 
surprised to see the "note" written in blue magic marker. Obviously the 
repair was done during the Vietnam war.  It brought back a lot of 
memories from my time in the draftee Army during the late 60's . (I was 
not a draftee)

As for the R-392, it is getting better. Someone had messed up the 
synchronization of the gear train, Veeder Root counter, the PTO etc.  I 
went back to the beginning and  re set the counter, checked all the cams 
and tweaked them back. Then I adjusted the Oldham coupler so that the 
PTO would read correctly.  When I was done, my brain hurt!
