Brad, I love that tube but it will not work in my Eros with the servo circuit removed. It just doesn't have the same output voltage (?) for some reason. I've been using Tele's in that Eros and love them but they are getting harder and harder to find good, quiet tubes. Maybe I'll need to put the servo back in. The Eros tape I had used them and didn't have a problem with the servo in place.
