Emerson NR303TT 3-Speed Turntable Repair.

Unraveling some of the mysteries behind these modern type turntables. Emerson nostalgia 4 in one unit with a non-functioning record player. This model turntable has the auto-return feature, & is fitted with a ceramic pickup. Motor is suspect, & steps are taken to confirm the issue. Testing the motor supply voltage, & also, why is there a lack of amplification when switched to phono. Also piecing together just how the 3-speeds are created via. a 2-speed motor. Motor spindle, pulley, platter sizes, types, etc., all play a role in determination of the 3-speeds. Motor was defective on one unit. A second unit was used to determine the value of the motors shunting resistor, (22 ohms), after suffering discoloring from running with the shorted/defective motor. Suspect an OOB-type failure, or not long after. Turntable showed little, if any use. Both units now function proper.
