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.
