Turn the set off for about 7 seconds, and back on. Does the width take a while to fill back out to where it was, or not? If it does, it's likely the H out tube.

(The '7 seconds off' test can also reveal borderline weak H osc., 3.58 color osc., Vert out, RF amp tubes, etc.)
I subbed in a spare NOS 6JS6C tonight and unfortunately it made no difference. I also swapped the damper tube.
