  1. Unit is not plugged into an AC adapter (do not have one), but used with an AA NiMH on sidecar. Have tried recording with unit powered by AA alkaline and lab power supply (1.5V) and behavior is exactly the same. Ended up measuring all voltages (except charging) and they are as follows (unit powered with 1.5V): VC1 L - 2.3428V (spec 2.35V +/-5mV) - out of tolerance VC1 H - 2.7423V (spec 2.75V +/-5mV) - out of tolerance VC2 Lo - 1.423V (spec 1.3V +/-5mV) - out of tolerance VC2 Hi - 2.543V (spec 2.55V +/-5mV) - out of tolerance REG1 - 2.15V (spec 2.15V +10mV -5mV) - within tolerance REG2 - 2.198V (spec 2.2V +10mV -5mV) - within tolerance REG3L1 - 1.1936V (spec 1.2V +/-5mV) - out of tolerance REG3L2 - 1.196V (spec 1.2V +/-5mV) - within tolerance REG3H - 1.5442V (spec 1.55V +/-5mV) - out of tolerance VREC L - 1.1215V (spec 1.12V +25mV -10mV) - within tolerance VREC M - 1.222V (spec 1.22V +25mV -10mV) - within tolerance VREC H - 1.4908V (spec 1.52 +60mV -10mV) - out of tolerance Since the test points are on the back side of the board it's hard to test with battery, but can test with lower voltage. In regard to seeking noise, are you reffering to noise during recording ?
  2. Hello everyone ! Have been struggling with a MZ-N910 that reads discs perfectly, but is unable to record. Symptoms are the following: - in analog input mode, the recording starts but after 1min or so it throws REC ERR error; - in netMD mode, the recording starts but progress remains stuck; - spindle speed can be heard going constantly up and down, like a CD player struggling to read the disc; After lubricating the spindle motor (watch oil), I managed to get a full disc recording when unit sat upside down. However was unable to consistently reproduce this behavior. Before lubricating the spindle motor, unit was also throwing a MEM OVER error which has disappeared now. Checking the unit for stored errors, I found this (see picture attached). However after clearing the errors, they do not re-appear.
