N9ZQA & Orthophonic, thanks for finding that info!
I had to dig into this last night. First I tested the crt-all 3 guns are good! It is the original Admiral branded, RCA built, crt with a date code in the 3rd quarter of '63. A mix of different tubes in the set, all caked with tobacco soot. So, I pulled the H.O. tube & damper and gave the set a soft start. At about 90 volts the breaker on my iso-tap tripped. I tried a couple more times but it wouldn't hold. I felt the filter caps and one was warm. Well, pulling the chassis is never fun but at least I had pinpointed the problem. Pulling the chassis wasn't too bad, similiar to an RCA. I changed out the 4 sections, putting them on a terminal strip. The adjacent can had one section replaced before but the replacement had lots of age on it, too, so I swapped it out. Besides, the last guy had paralleled it instead of clipping out the old one. I put it all back together and tried again. This time I had audio when I powered up...I installed the HV tubes and went again. There was not sign that the HV was running, and then the breaker tripped again. Now the other can is warm to the touch, so I pulled the chassis again. (nothing was bolted down, so it only took a couple minutes) Tonight I'll swap out that can, and maybe the 2 smaller ones in there as well.
At this time I usually find myself wondering what retired a set. I would have blamed it on the caps but the breaker on the set hadn't tripped. So maybe it was a HV problem, and the caps are just from years of storage. If the HV doesn't come up then I'll start with swapping the 3A3 and go from there. I'll post some more pictures, including the chassis, later on.
One reason I like this set is that my first color roundie was an Admiral. This was in the early 90s (I watched the first gulf war unfold on that set) and if I had known then that cataracts were repairable I would still have that set. I think it was a little older than this one.
