RCA CTC-140 Blurry Corner

[jstout66]

Picked up an otherwise nice RCA CTC-140 console. The picture isn't bad, but the focus is "bad" on the lower left corner. It's mainly noticable if there is text. Has anyone else run into this problem, and is there a fix? I liked the fact that it is a stereo set and has a ton of inputs. Also like the cabinet style better than the older System 3 I had been using. However, the Zenith has a picture that blows this one out of the water. (which is surprising as those 25" tri-focus tubes weren't that good as they aged)

*ugh.. I see I posted this in the wrong forum. Meant to post in S.S. Sorry!
