[R-390] New revision of my document 'My R-390A Cosmos PTO Observations'

[Fred Moore]

Larry, 

That is a great explanation of restoring the R-390A Cosmos PTO.  I have two
R-390 PTOs to look over inside.  I am wondering if the same approach applies,
or if there is something I need to do differently. 

Is Electric Radio the source of the R-390 CD?  If so, it looks like they are
at -0- right now.  There may be an opportunity to update it.  Then I will buy
one. 

-Fred

Hi All,
I did a major update to my subject document and thought a better location
for it would be in the 'Tutorials' section of our R-390A disk.  The
original is pointed to from the 'Pearls of Wisdom' index. I added a lot of
information about the linearity mechanism in it.  You can find it in the
'Tutorials' section with this link:

Or, you can look at the new version directly with this link:

Happy Holidays.

Regards, Larry
