All caps are fine except I did replace a .039 which comes off the plate of the vertical amp and goes to the red cathode of the CRT. The original the maroon drop cap tested OK but I had a cap on hand and replaced it. Dont think it will make the vertical any higher though..

I would probably replace that resistor. Also how does the B+ look? 380V? Also I might replace c169 even if it tested good. Also don't rule out a weak tube.
