Thanks all, personally I'd choose a desoldered pull from an old board over an uncertain 'new' source, but I have tried the 'recent' one and it seems fine, in fact I left it in the board rather than bother to swap it back. Back in the day I did have at least a couple of genuine spares, I've no idea where they went
Is there a way to embed videos properly so they dont show as a link? I tried the usual tags to no avail
Cheers
Phil
