[R-390] A surprise when I opened my R-392

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!
