Default Re: Transformer safety?

Some time back Chas Miller did an article in which he described how to isolate the neutral return from chassis by creating a bus bar. The chassis is connected to the bus bar using Class Y capacitors as normally you cannot isolate all components such as the tuning capacitor frame from the chassis. The same principle could be used for a set with an auto transformer. The article was published in Radiophile of course and someone will probably remember which issue. It sounds a bit complicated but for many sets it probably isn't. Many American sets were built like that in the first place.
