I dont think the 9-470 had the problem. As I remember it was on
first year "custom" series sets. I think they updated the IC but I
dont remember a part # change. IIRC it was a Hitachi IC & there
sets looked orangy too. If you do a 9-470 I would be careful &
refer to schematics first.
Sets with the switch looked fine with it off. Thats what told me
something was up. Same board, IC & CRT but the pix on the
cheap ones looked like dog doot.
For purity issues on these usually you need a small correction
magnet on the bell. Someone else here a few weeks ago did
his & used a piece of refrigerator door gasket magnet.
Very clever.........And came out perfect !

In storage, I have quite a few 80s Zeniths with some using the 9-181, so I'll have to look into the mod on those. Some have a 'chromatic' switch, which is basically an auto color ckt.
