The electron emitting surface on the cathode was a bit thin on the trinitrons, and when it wore to the point of needing a rejuvenation there was simply no good surface underneath to use...So rejuvs could burn all the cathode material (which was already used up anyway) off...That is what I gleaned from previous threads on the matter...For someone that types rather long posts that often are about the same 3-10 things you sure don't seem to read much...
