Should i bother restoring a zenith?

First thing is first on a HV corona/arcing issue (or a restoration for that matter) clean the inside of the HV cage including all parts inside as good as you can without breaking anything(conductive dust and gunk can cause all sorts of arcing/corona). After the cleaning if the issues continue run the set with the HV cage open and or partially dismantled and look for arcing/corona in a dark room with the set on. Once you locate it a picture of the area it is coming from will tell us what it is and how to advise you to fix it.

Thanks E.M., that sounds like the logical thing to do. I am sort of jumping the gun I guess as I have the set in a tight spot in the kitchen sitting in the floor on its side doing all the work I can do without being able to move it around much. I guess the good thing about a corona/arch issue is that you can see it in most cases. Removal of the cover and testing the H.V. related tubes will be the next step.

I want to be sure that the fly is running as cool as it should. The ammeter remains connected to the cathode of the H.O. tube, so I can watch for any issues there. I need to run the set for a long enough duration to let things sort of stabilize as they often do. Flys are supposedly notorious for collecting moisture, but I don't really know the symptoms of moisture in a fly.
