Melting rubber, crumbling rubber what nots, I seen those, first time
last week for latter, former many times in my life.

Found two RCA PIP modules had that brown, sticky goo everywhere from
where tan rubber bumpers used to be, YUUUK! RCA used them to keep
tin shielding from shorting out on solder side circuit board. Goo
also sometimes causes problems. Have to clean those off.

And that PIP modules were used in CTC169 chassis (both for direct
view tube and tv projectors). Manufactured between 1989 to 1996 era.
About 10"x5"x2", pocked with holes for ventilation, usually 3 to 5
plugs in one row on one side.

What kind of cleaners really successfully dissolves that goo? Have
to do it easy and quick. CTC169 was produced by the zillions and
wildly popular back then and we still see them all the time and it's
a good money maker so far.

By the way, rubber bumpers still used in many RCA later chassis like
177, 187, 19x (most recent versions that just stopped in production).

Cheers,

Wizard
