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. Berry Kercheval Zehntel Inc.
