I attached a couple wires to the small DC motor that controls the tone arm carriage, used a multimeter to measure the voltage going to the motor. More complicated than i expected, the voltage to the motor varies from nearly 7 volts to barely over 1 volt. the high voltage being used for manually moving the carriage to different tracks. The error control voltage while the record plays varies between 1 and 2 volts and the motor is at times off but it's a very short time, second or less, it's almost always on.
Not sure how to measure and record the motor voltage since there is the conversion time and storage time to be concerned about. I'm not sure I could get any meaningful data with the picaxe.
While writing this i'm listening to a record, the kenwood sounds very good and it's tracking a record well despite it being warped.
