[R-390] PTO endpoints

[Jim Brannigan]

My COSMOS PTO endpoints were long by 6.5 Kc.
I attempted to reset them "by the book".  It quickly became an exercise in futility.  Trying to thread a tuning tool through the gears and into the hole behind the coil can was not going to work....

Finally, I pulled the PTO, set up a quick jig and connected it to a frequency counter.  Many iterations later I got the endpoints down to 1.5 Kc. long.

I may have to live with the 1.5 Kc. for a while.  The top of the core seems to be broken. (I really can't get a good look at it through the front)

The "junke box" has some cores that may fit the coil, but they are of unknown permeability.
Has anyone else run into this problem?

Jim
