The Zenith was just an odd set. Chassis number was even unconventional will the rest of the Zenith line. It didn't have 20 tubes.  |
This is the cross over year for chassis numbers.
Used to be tube count then model year.
Switched to screen size then model year.
1971 had both formats. Model numbers also started to change to
year letter - nonsense screen size ( 40## =19", 47##= 25" etc )
To real screen size but that change took at least 5 yrs before it
was across the board.
So anyhows the format for this chassis is
20 = screen size
B = model year 1971 ( released fall of 1970)
C = color TV
50= consecutive number, the higher the # the higher the feature level.
