Russ... once the endpoint adjustment slug is fully in and out of thread.
you've got to have the PTO  apart  and put back in.
I've done a few COSMOS  and in lieu of  removing a turn off the  EP coil
I've now  opted for adding another 10 pf in series with the one already
there... 
 The resulting 5  pf then  across the  coil does the trick with no obvious
side  effects .
The linearising screws  are a PITA--- you may be lucky and find yours have
slotted heads... I'm usually unlucky and find that mine have a miniature
Bristo flute socket head. 
If you go the  whole way and disassemble, make  sure you get the  disc with
these linearising  screws is back in the  same position.... some models
don't have  screws in all the holes so you end up with a problem.
Get  full story on revival of a  COSMOS
from the archival information 'A Journey through the Cosmos' (PTO) by Jim
Miller.
Cheers
