[R-390] Great R-390A Maintenance and Troubleshooting Handout

[Roy Morgan]

Mister Mike,

Indeed a great find - thanks much!  
(I don’t see it yet on Wu Li’s Pearls of wisdom - FAQ/Technical References pages: http://www.r-390a.net/faq-refs.htm <http://www.r-390a.net/faq-refs.htm>. )

With so many manuals out there for the R-390A, I wonder which one is used in this troubleshooting handout.  There are enough references to diagrams and page numbers so a diligent person could figure that out.  (I would be able to add that pub number into the PDF file.)

I’m going to print this a section at a time, and have it handy when I start restoration of the three radios I have at hand.
