GENERAL INFORMATION

The Zenith Cobra-Matic Record Changers are designed to play in automatic sequence a
stack of records and shut off both the changer and amplifier after playing the last record.

The Changer plays at four different turntable speeds; 16 2/ 3, 33 1/ 3, 45, or 78 r.p. m.

As many a ten 12", twelve 10" or any assortment of 10" and 12" records (providing they
are of the same speed and same type of groove) may be intermixed in any order.

A stack of twelve 7", 33 1/ 3r. p. m. records or a stack of twelve 7", 45r. p. m. records
(with the use of a "45" Adaptor Spindle)will also play on this changer.

Record separation is accomplished by movement of a finger in the center spindle. This
finger directly separates records having a 1/ 4" centerhole and actuates the knives and shelves
of the centerpost used for the playing of the 45r. p. m. records having a 1 1/2" centerhole.

This Changer is to be connected to an outlet supplying 110-120 volts, 60 cycle AC only,
unless otherwise specified.
