Question regarding the 1957 22 inch CBS color set.
 

If you look at the tube chart and chassis on the ETFs page regarding this withdrawn set (http://www.earlytelevision.org/cbs_2...ctangular.html) it looks as though both chassis are identical, or nearly identical, to those in the CBS 205.

Does anyone know what, if any, changes were made to sweep and converge the oddball CBS rectangular jug?
