I took a look inside the top, and saw that all tubes except for the CRT are missing, so a tube hunt in our tube room is needed. Then, there all the electrolytics! Gonna have some fun  ! Going to return to check the CRTs later this week, and will proceed from there. Any encouragement will be VERY welcome!

Checked emission of the two CRTs today. The 21FB has very good emission from all three guns. It had been replaced, but couldn't see any date code yet. The 21FJ checked "dead"
, but I'll return next week with a different CRT tester that has a more "gentle" restoration procedure. Didn't use the "brute force" method of my older B&K. I'll also start pulling tubes from storage to use on the FB monitor. More to come!
