Puck (adapter)
A puck is an adapter that is used to play a single with a large center hole (1½ inch = 38.1 mm) on a turntable with a regular pin (7 mm). It has the diameter of the central hole and a hole in the middle with that of the mandrel. It is placed on top of this and so centered. Another possibility are reducers, so-called "stars", which are pressed into the center hole.
DJs often use singles , especially in funk and reggae . There are various particularly heavy versions of pucks so that they do not slip when they are put on. These are far superior to the pucks supplied with turntables. Due to their heavy weight, however, they can cause the turntable to come to a standstill if incorrectly placed.
background
Adapters became necessary because two competing record formats came on the market and neither of the two could replace the other: On June 21, 1948, Columbia Records presented the 12-inch (30 cm) long-playing record with 33 ⅓ revolutions per minute and a small center hole . In 1949 RCA Victor followed with the 7-inch (17.5 cm) record with 45 revolutions per minute and a large center hole. The former prevailed in the episode for albums, the second as a single. One reason for the single's larger center hole was its use in music boxes , which required a robust construction.
