[Johnson] Pacemaker

[David C. Hallam]

I am looking for some information about the slug tuned coils in the
Pacemaker.

On the Part List there are 2 type of Iron Slugs listed; 22-1210-1 27 each
W18 EE 5005 Iron Slugs and 22.1210-2 3 each W19 EE 5006 Iron Slugs.  Does
anyone know what the composition of these 2 types are and where each type is
use?

I am refurbishing a Pacemaker and may have to replace some slugs due to
broken adjusting screws.  I  need to know what I am looking for.
