Here is a quick Hi−Fi
Quiz for all you audiophiles out there. Although it appeared in a 1955 issue of
Radio & Television News magazine, save for question #10 all of Q's
and A's still apply to today's equipment. Even that one can be easily guessed. Q4
might seem a bit foreign, but think of the "groove" type as applying to 78, 45,
or 33-1/3 rpm platters and you'll do OK. Question #7 could be a baffler (pun intended
- you'll see how) were it not for one obviously invalid option that it takes an
RF guy (or gal) to recognize its inanity. Good luck. BTW, I missed Q1, but should
have known better.
