If I'm not mistaken, a year or so ago I was at a trade show and saw a transformer made by Bertonee that had a nice "Jellybean" effect. Not sure if it was a prototype or if they market it. I've used some of their very small 'formers (+-1"x2") for a couple of feet & had good results... If anyone can confirm or dismiss the "Jellybean" 'former, let me know... Tom U.
