BE-5 schematic source

[Rich Post]

The schematic for the BE-5 is here on a Brit site:  AFAIK it dates from 
before 1964 and is therefore public domain in USA.  Heath manual copyrights 
were not renewed according to my data.

Oh, And any schematic you REDRAW in a more modern fashion is automatically 
copyrighted by YOU.

You cannot copyright ideas, only expressions thereof.
