My new Zenith 25EC58!

[zeno]

G-2 control fails were common from the 4 tube hybrid
through the upright CC 2 chassis. All same values but
one had solder lugs & CC2 used spades that go into
terminal strips.

Chromacolor goes back to late 68. Black matrix with smaller
dots. Over the years more HV up to 30KV, smaller dots &
darker screen glass for better blacks & contrast.
CC tubes worked down through the 19" hybrids and the 16 & 14
tube sets as a step up option.

IMHO the control area was the best looking non-remote panel.
IIRC only on some E & F consoles IIRC. Slider has a small hole
in it for chromatic adjustment. Came with a plastic screwdriver.

IIRC lamps can be changed from front. Pull knobs then a few phillips.
Probably #159 or #259 in Zenith tradition....
