Yes i have change ribbon cable and remove solder point on laser head. I have next kss213c, same one like from photo. It works but it work like he dont have power, when i hit on table it loose track, when i put more than fiveth sixth track or more it is loosing track and optics are vibrating. From my friend i have rotel 971 cd and it have same kss213c laser, works well, but it to loose tracks when i hit table, of corse not much! On sfp101n it works and even hiting table dont impres it. Mayby shigariki dont have much power for kss?
Okey i have next kss213 laser head, this time B version. I have put in in kss213 mechanics . It work but still some problems witch higher tracks. For example 10 track thr lasser have problems and it is searching. And dont se more than 10trakcs on this,So i have hited a littlem on top of the cd puck so it gets litle lower. For now it see all 17 tracks and works better. But what is a reference distans from cd to mechanical sheet metal?
