Another interesting note from when \\I// used to work at the
radio station at my university (U of CA at Riverside -- KUCR,
88.1 FM "Bottom of the dial, bottom of the pile").  The main studio had
3 big Gates turntables, whose platters were slightli dished in the center.
The center spindle was machined into the platter, and was stepped, with
the bottom being 45 RPM-hole-sized and the top 33-RPM-hole-sized.  When
12 inch 33's were played they were supported on their rims and fit the smaller
spindle;  7-inch 45's dropped into the dish and fit the lower spindle.
7-inch 33's with small holes were a problem;  we generally dubbed them to carts 
before airplay.

Incidentally, broadcast turntables have a few extra goodies not found
on home turntables.  The main differences are a clutch to allow cuing and
a MONSTER motor that will bring the 10 pound platter up to speed in a quarter
revolution.
