Not to get off topic (The OP doesn't seem to be following this post anyways), but I had another one of those old Black Plates in my TwinFace. I think it was a 1958 RCA Long Black Plate (Exactly where you'd think it would shine), and it really sounded like junk. So far this MashAll is the only place I've put one, that I've ended up keeping it there. I can't remember what made me try it, but it instantly woke this Module up. I liked it before, but as soon as I put that tube in, I really fell in love with the thing. Now I cant remember what tubes I originally had in the TwinFace... I gotta start writing **** down LoL
