GOOD OR BAD JUDGEMENT METHOD OF THE PICKUP
1. LD current : 20 to 80mA TYP : 40 to 50mA
Measure both end of R249 on the MAIN Assy in the play state. (Fig. 1)
There must be the value that divided the measured value with 23.5 Ω within the numerical value mentioned above.
2. Focus coil DC resistor : 7.0 ± 1.0 Ω
Pull out the flexible cable from the side of the pickup Assy.
Measure the resistance value between the feet(F+, F-) of the posts.
It must be within the above mentioned value.
3. Tracking coil DC resistor : 6.0 ± 1.0 Ω
Pull out the flexible cable from the side of the pickup Assy.
Measure the resistance value between the feet(T+, T-) of the posts.
It must be within the above mentioned value.
