Wells Gardner 2775 Monitor Board, New Flyback & Cap Kit

Howdy! This is a used Monitor chassis from a 27" Wells Gardner 2775. Medium Resolution! It works,but, it has brightness issues. I put in a brand new cap kit and flyback from Bob Roberts but the picture did not seem to be as bright as it should. Now, I am thinking that it could have been the tube. I really do not know and I have run out of time on it. Of course, sold as-is.
