Big differences, no pun intended! There were 3.5 and 4 inch Image Orthicons. They basically had photo multipliers built in so the video signal was formed very similar to an old MK3 front end. Plumbicons were electrically and physically identical to Vidicons except for the target material. The target formed a raster of capacitors which were discharged by the electron beam - very simple compared to the Image Orthicon.

Here's a great site I found. http://www.oldradio.com/archives/hardware/TV/RCA-TV.htm
