Thanks, good suggestion.
I have to admit I havent dared to open it yet, I tend to start with the wrong screws and things fall aport :-)
Will I easily be able to identify which chip is which And there is no soldering, only click-in or whatever the term is
If it proves to be that chip, are CEM 3396 chip still available
regards
