100° Picture Tubes

The Zenith you are looking for are mostly known as System 3. They
used an EFL 110 deg in line CRT. Chromacolor 2 ( CC2 ) sets used a 90 deg
delta gun CRT but it gets confusing !
EFL sets first came out in late 1976 on top of line 17" & 19" using
a CC2 style chassis. By 1979 almost all sets had EFL jugs 13", 19", 23" & 25".
These used the System 3 style chassis. Due to cost EFL was phased out
starting apx 1983. The sets are very common, they sold more color sets
than anyone in the US. Best bet is if you think you found one post the
model number & we can look it up.

Unfortunately, that is not what I'm searching for.

I'm looking for TVs with 100° CRTs.

Thanks.

Extended Field Lens. Basically 3 focus grids instead of one.
Panasonic & a few others also used them on some of there high end sets.

They also came up with FTM or Flat Tension Mask about that time.
Only in ZDS monitors & some military apps. they were 2K bucks new. Zenith told us if they used it in a 13" TV they would go for $1000 just to break even. Pix was on par with the best 35mm film. They became the flat & square CRT's of later years such as Sony Wegas.
