Ah thanks for letting me know. I read this too late. I found my way to the French matra passion forum and from there I was redirected to the Belgian new production. They use the new blade fuses although I think the glass ones on the original board look best of all options. Perhaps one day I'll swap again.
Can you give us the link to that Belgian product here please, as I'd like to see it, as might other owners. However, without seeing it, I suspect that it still uses the original edge plugs and therefore still would have problems if the terminals in those plugs are broken, and not making a positive contact. Am I right or have they corrected for that too?
Here is a photo of one of the original Murena boards, that I have modified with both new edge plugs and sockets that are soldered to the board, so the connections are really good; and this one also has the glass fuses replacing the original horrible continental fuses, for much better contact there too.
