[R-390] R-392 Dubrow PTO endpoint

Mon, 8 Apr 2002 05:56:43 -0700 (PDT)

I've never worked on a Dubrow, but I think it is the same as a Collins.

This is a very common problem.  One author wrote that this mod is not worth
doing, but I can't disagree more.

What you'll need to do is remove the cover, find the PTO endpoint adjusting
coil, and remove one turn from it, and then start over.

I find on some PTO's that it is easier to make a new coil than to trim the old
(Cosmos in particular), but that will be your call.  

This will keep you in business for the news 30 years or so.
