I am currently trying to fix a PP-7B power supply and decided to clean up the schematics a bit and have them show up the correct way in the pdf file to make viewing them on a computer a little easier. Anyway thought I'd upload them in case anyone else finds them useful.

What did you use to clean up the schematics?
 
Probably would just be better off redrawing them in some CAD tool.
While a cad drawing would be clearer, the file format should be as universal as the pdf. I wonder if there are free cad drawing software that can save and read pdf files.

Of course if your going invest time and effort into a project like this. Measurement and signal points of references would be helpful to those who are attempting to repair this kind of power supplies. Maybe a theory of operations to those who come after us.

Almost anything can print to pdf these days -- if nothing else the CutePDF driver on older OS'es gets the job done.
