[Collins] Identifying BBs

[Dr. Gerald N. Johnson, electrical engineer]

I'll confirm. Those black cylinders are Black Beauties. These are the
distributor style parts, instead of those with color coded bands. At
some point, probably after the 32RS1 was made they were made with a
combination of polyester and paper dielectrics and were much improved
over the original oiled paper capacitors.

And the large brown cylinder is an aluminum electrolytic, which has a
shorter lifetime than black beauties. I've had a few of those explode
and they really make a mess filling the area with shredded crepe paper,
aluminum foil, accompanied by the conductive electrolyte (and the crepe
paper is saturated with electrolyte). A real pain to clean up. I don't
use old electrolytics, nor reform them. New date codes for repair and
construction or I don't do.
