The System 3 first & second gen sets used EFL CRT's Basically 3
focus grids instead of one. The bad CRT's were regular in line guns.
They made them for about ten yrs & they were fine. Then abt 1993 they went to hell. I blame Gold Star. They got more & more control over Zenith
& kicked them under the bus. IMHO all they wanted the HDTV patents that
Zenith held, almost all of them.
