Convergence ?

Component drift. Most notably the selenium stack on the conv board if it's still original.

Yes the selenium is still in this set was going to change it but decided since the convergence was good I left it.

Dittos to Mr. Coot.
Diodes or cold joints on the conv board. I saw a few 14 & 16" Zeniths where
the blue IIRC would pop in & out, it was the conv yoke itself. The diode pkg
can be changed with a direct sub ( ETG etc.) , OEM or separate diodes.
