Smooth noob move on a Zenith

Hey guys...
I cannot believe I did this.

1970 model Zenith color with the 20BC50 chassis.
I was replacing a leaky 50v 100mfd cap.

Well I soldered it in backwards...... The cap didnt blow up but since fixed the reversed cap and replaced it with another new one just to be safe. Well, it seems that the raster is like keystoned in from the bottom and it's only about 4" in height. I get a picture, chroma, luminence, everything is there, but I messed up something. Any ideas where I should look? I have tested resistors and caps in the accociated path of the cap, and there appears to be nothing physically burned.
Thanks!
Shawn

Actually does anyone know the value of the resistor (cooked in half) that comes off pin 11 of the 6LB6 Horiz output tube? starts with orange it looks like.

Thanks!
