Good info, thanks again everyone. So, I need to find a CRT tester basically. I say that because if this Sylvania (rebuilt) CRT is one of their bad runs, then the project is a boat anchor. I am hoping that the set got the newer CRT during it's last couple of years of service and Sylvania or not, it will hold out for a while. If the tube is good I think the set is worth the time and $ involved in circuit repairs. Both a CRT and re-cap job to me would just be beyond reason for what I guess is a fairly common old Zenith 5111. I took the set in, mostly to save it from possible landfill duty.
I have five other sets that need restoration to varying degrees! So, hopefully I will see some signs of life pretty soon. Maybe it will be a keeper! I think the Zenith is a nice looking set that is not too bulky. It certainly could not be more plain if it were a Muntz!
