[R-390] R-390/URR Z-503

[James A. (Andy) Moorer]

  They must have had winding tables for L514 - and all the other 
inductors/transformers in the unit. That would have been required for 
military usage, and certainly for outsourcing the manufacture of these 
units. Do I gather that such a document for the R-390/390A hasn't showed 
up yet? They have to be out there somewhere.

I was recently startled to run across one for the SP-600.
