1968 Zenith 20Y1C50 chassis - advice needed

[zeno]

When you have a stage that quickly burned up parts its good policy
to just change the tube involved. Odds are its shorted or int shorts.
IIRC with a bad VDR you would get a bend in the pix at the bottom
& poor / no regulation.

Tube type Zeniths are known for bad spots on the vert. size, HV adj , &
G-2 ( screen) controls. The bad G-2's went through the CC 2 sets.
They were so common I still remember many of the part numbers.
