Change it ALL AT ONCE !

One of 3 things will happen
1) everything will blow again in one microsecond.
2) set will work perfect then usually withing a week blow everything
without any warning.
3) the set will work for years more.

HINT most Sony color sets between apx 1975 & 1980 used the
SG613 & 2sc867. If you get one with a bad CRT but the set works
pull those parts, they are not cheap. Dont reuse the damper.

LFOD !

The KV1212, CA 1972 uses two 2SC867 for the horiz output, IIRC.
The newer models that used the SG613 were a rather big headache. I did everything by the book, the set failed a year or so later. I checked the set out and it seemed like the same failure. I told the owner it wasn't worth repairing, as I cant see the picture. Those CRT's didn't fair that well.
