All Diyaudio Threads about not available Optical Pickup's from Sony's KSS-Series

[tiefbassuebertr]

There are many threads about SONY's laser heads (optical pick up's) from the KSS-Series. I have started also some threads in this case. The reasons are clear. First the no longer availability of most of them and second the big error rate sometimes after a short time of use. In general - from all laser units that I know, Sony's laser heads above KSS-120 by far the worst of all (life time, reliability), even the models for the ESPRIT series like KSS-272A. Two main reasons are therefore responsible:
1) the suspension of the collimator lens (plastic leaf spring instead spring wire)
2) the diode itself
Obviously it can happen sometimes (fortunately not often) that other laser head manufacturers than Sony also used such worse Sony diodes. If by such older CD players the RF level very low, you can assume, that a Sony diode is inside.

By JVC-, Pioneer- and Hitachi laser heads after more than 20 years in use there are still virgin light power (after lens cleaning) and thus good level by RF signal. Also the tracking behaviour isn't impaired due collimator lens suspension without plastic.Unfortunately for most brands SONY was the main supplier of optical pick up's.

After a certain time this threads are relatively hard to find. Therefore at bottom an URL overview of all threads from diyaudio about SONY's KSS series.
