I never use ribbon due to corona. Take a 5 sec B&W 400 ASA exposure and you will see what I mean. I did with earlier coils and the photos almost scared me. High level of degradation on the sec coil. Perhaps for occassional operation it's ok, but I would not make a commercial unit with sharp edged ribbon. Corona much less for copper tubing. Dr. Resonance
I beg to differ from this point of view:The Museum coil features sharp edged ribbon, and it was put into service 6 years ago. It has been running daily, ever since. None of the degradation you mention has ben reported, or detected by myself.
