As I restore this ET-3400, I am curious if anyone
knows what
kind of filter material Heathkit provided that sticks to the
TIL312 7-segment displays? Mine have 4 of 6 displays
covered, and 2 displays bare. It seems to be some sort of
adhesive red tape or film, but I have no idea what to use for
a modern substitute.
Thanks for any tips.
Two ideas come to mind - lighting gels, used in stage lighting, and
Kodak makes lens filter gels in a huge range of colors. Both these items
will appear to be colored sheets of plastic. In the case of the Kodak
product, the "pass band" of the filter will be narrow and precise (an
exact shade of a certain color and it won't pass much else).

I should be
more precise in my description of the material in question. The
ET-3400 has no bezel around the TIL-312 displays. The red filter
material provided by Heathkit was pre-cut to the exact size of the
face of each display, and sticks on by its own adhesive. It seems to
be quite soft (vinyl-like as opposed to mylar-like) and quite thin -
much thinner than scotch tape.
I'm sure I can find some sort of red non-adhesive plastic, but I was
really hoping to find the same sort of material they used so the
displays match.
Thanks,

How translucent or opaque is the material? I am thinking about maybe tail
light repair tape used on cars. It is red, thin, fairly opaque in appearance

just about any auto parts store. May not be exactly what you are looking for
but may work out well anyway. Then again it may be too opaque.
Just a thought,

Also check out the colored acetate available at art supply stores.

Classic acetate masking material is a bit orange, and also thin and
crinkly, but it may serve. And art stores are likely to have other
types of colored plastic.
