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
