Just completed a restoration of this 1949 Zenith 28T960E Basket Weave porthole TV with a 28F20 chassis.
It was a pretty straight forward restoration, with no real surprises. The 12" crt was rebuilt at some point long ago, and is in decent condition. I did have some trouble with the sound and discovered that the problem was the typical Zenith Mica in the IF can issue that you see so often in their radios of this vintage. After working through that everything else fell into place.
The cabinet was in pretty good shape and just needed a good cleaning and polishing to bring it back to a presentable condition.
Overall I'm happy with the set and the performance. The picture is a little on the soft side, but I guess that's to be expected since the crt is not in the best condition.
