RCA Victor 21-T-8205 issues

[Phil Nelson]

I'd start by replacing all paper caps in the vertical circuits.

After doing that, I'd go to the service manual and look up the adjusters for height and vertical linearity. (Your pictures show a moderate problem with vertical linearity, where objects in the top of the screen are vertically stretched compared to the bottom area.) Note that these adjustments are somewhat interactive, meaning that adjusting linearity may affect the height a bit, and vice versa. You may need to go back and forth between the adjusters a few times to get the height and linearity just right.

Looking pretty good, otherwise.
