META - G9 Tube Micpre

This is a meta-thread, made to allow you to keep track of the posts concerning this single issue - I will continue re-editing this first post. All should be contained in this first post - which is re-edited regularily. Everyone is welcome to reply with comments and pointers to things they consider relevant. This will be copy/pasted into the first post, if the meta-keeper finds it relevant. (We deeply dislike censorship, but here it seems necessary for the sake of overview). On a regular basis, I will delete all posts but this first one, and bump the thread to the top.

Hi Solker,
