Consider youself fortunate - Capacitors do fail when they have not been
re-formed. We found several such instances in restoring the PDP-1 - and I've
seen it on other older systems (like my former PDP-12).
BTW: I am "happily" envious of your acquisition. The CDC-160A was my first
"home computer" back in the late sixties. I was working in IBM's
Poughkeepsie System Development Lab on System/360 - but I wanted a home
computer so bad I could taste it. I shopped around - and a used CDC-160A was
all I chose to "afford". Mine, however, used a Frieden Flexowriter for I/O
along with the usual PT reader and punch. Sigh, fond remembrances...

I second Eric's "motion" that the LA Typewriter folks are really good - and
would add they are interesting folks. It's been a family run typewriter
business in Los Altos for many years...

That's really great! - the platen's often show wear, tear and cracks.

Try to be close to the original as possible in type, finish, etc...
Best wishes on you restoration!!!!
