ABSTRACT:
A turntable mounting for a record player comprises a platform for rotatably supporting a turntable. The turntable has three angularly spaced holes, and the shanks of bolts pass freely through the holes and are secured into sockets in the base. Compression springs on the bolts extend between the platform and nuts on the bolts, so that the platform is resiliently supported. During assembly, the nuts are adjusted to provide the desired tension in the springs and are set so as to turn with the bolts if the latter are adjusted to effect levelling of the platform. In this way, the setting of the nuts and thus the tension in the springs is not altered. Should the tension in a spring require to be altered, the nut can be held by a spanner while the bolt is turned.
