• Notes
• The Zenith Modell L565R is an AC Operated 5 Tube Radio-Phono Combination Superheterodyne Receiver with 3 Speed Automatic Record Changer. The attraction of this unit is it's cobramatic stroboscope record changer, which is completely unique and ahead of it's time, as it allows to adjust the rotation speed continuously and without any steps from 13 to about 80 rpm continuously - and it has a stroboscope wheel in the center of the unit, which gives read out of the speed at which the unit actually runs at. Record changing cycle actuated by solenoid. Cartridge type: 991, available in either: 1 mil (LP), 2 mil (for either), or 3 mil (78) stylus.
