Abstract
An auto return record player is provided which can be simply and economically adapted to function as an automatic set down player. Either the auto return player or the automatic set down player is capable of playing a record on the turntable twice and then returning the tone arm to the rest post and shutting the machine off, the tone arm being automatically set down on the lead-in groove of the record between the first and second playing cycles. The record player is of the so-called quarter panel sub base type and may be assembled in a main base or cabinet without removing the turntable from the quarter panel sub base. The record player also has a 45 rpm record adaptor which is provided with an integral stub centering spindle portion for small hole records which may be grasped to lift the adaptor to a 45 rpm large hole record playing position, the adaptor covering a separate inexpensive stub shaft which acts as a bearing for the turntable.
