Chromacolor II

Yes, memory can be a funny thing. The 4-tube hybrid is neck-and-neck to be my favorite to the CCII. Still have a 19CC19 with the tube horiz and damper. 6FL6? I believe. That one probably has a better picture than this one but the CCII has much better HV regulation and may be brighter overall.
Meanwhile, my early system-3 stuff (9-160 based sets and the 'Z' line from '83-'84) still makes a fantastic color picture but when you take them apart, they are
so much cheaper of a build. Really plasticy and thin boards.

All Zenith color solid state sets used a tripler. Early SS colors
from RCA, Sony, Motorola & others used a tube rectifier.

Now a few IIRC's
The first SS B&W Zenith used a tube. A rare set.
The first SS 19" Zenith, 100% hand wired also did. Also rare set !
The next generation ( hand wired with duramodules) used a stick
HV rectifier.

Your set is a K-line. K-line also introduced the first gen System 3 chassis
on TOTL 19 & 25" sets. Next year, L-line the last CC2 sets were built out
as a low priced set. About a 6+ year run for CC2's. Not bad !
