[MRCA] R-553/ARR-8B Information

I have acquired a basically working R-553 VHF receiver.  That is, I can 
receive and display signals on the scope.  A previous owner apparently 
disconnected the motor circuits and converted the unit to 60Hz.  Not a 
bad job, at all, but I'd like to re-install the motor function and be 
able to align the thing.  The scale reticule is a bit faded and I'll 
need to re-do it, somehow.  I could use a manual, of course, but a 
schematic would get me there 95%. 

Thanks and Regards to All.
