I do know that Magnavox and Zenith used those white caps in the high voltage area, which tended to fail early. However... depending on when this was taken out of daily service, if it hasn't blown up by now, I wouldn't be overly concerned. IIRC it was the Chromacolor 2 chassis that had the problems, and Zenith did a huge recall, which I WAS involved with. Those caps failed fairly early in life. In repairs on the "newer" stuff ( after 1967 ) you are basically okay with the caps that are in there. Yes.. you will get many opinions, as some spaz and do a total recap, but, those sets did NOT use the ones that early sets did, so I'd hate to have you end up doing a needless recap on EVERYTHING.
4 lead caps were in 17/19/25EC45 chassii runs 401 and higher &
into the F line. Before run 401 they used the same seperate caps
this set has. Reason for seperate caps is if one or two open the
HV wont go nuts but you will see symptoms. 4 lead caps were meant to open
between the HOT E & ground or C to flyback to kill HV but it didnt
work. Small world a Sprague rep lived in town & had an Avanti
with 25EC45 ( or FC) & the cap went. He got the new Sprague
replacement & it failed !! Sprague failures were always an open
killing the HV or dead short.

I never saw or heard of a flat chassis cutting a neck. Had abt
5 EC45 chassis with massive damage. I think most were 19".
IIRC. The vert would fail & cause a lot of current through
the yoke cutting the neck. One of the reasons the vert had a fuse.
The flat chassis used a totally different vert circuit.
I also saw 2 Maggies with cut tubes, T993 ?? probably the same thing
so we just gave them back & told them to go to a Maggie shop.
