:I've always been somewhat in awe of the old Sprague Company's marketing names for their various lines of caps: e.g., Black Beauties, Bumblebees, etc., whose names refer to the caps' appearance.

:Their "Vitamin Q" caps were oil-in-paper caps, still highly sought after by audiophiles. They are good caps - many were sold to the U.S. military.

:I wonder if the "Q" was somehow a reference to the quality factor, symbol Q, for tuned circuits? A cap with low effective-series-resistance could help give a high-Q in a tuned circuit, right?
:
:But, if that were the reference, then it seems like it could have passed over most people's heads. And, the Vitamin Q caps were generally used for coupling and bypass, not in tuned circuits.
