I would strongly advise against changing capacitors unless you can prove failure. Changing caps WILL make alignment needed if they were not defective before replacement.
Changing resistors to 5% or better modern replacements typically fixes alignment issues if the original was bad, or barely changes anything if the original was good (provided lead dress is carefully kept the same).
I have on 2 CTC-2 and 2 CTC-4 sets fixed egregious alignment issues by replacing all resistors that were off tolerance or at the edge of tolerance with modern tighter tolerance parts....On the CTC-4s the sound, luminance and chroma were all so far apart from each other on the fine tuning that you could only get 1.5 out of 3 in good at once (you could get any 1 of the 3 in alone good at a different fine tuning spot) before resistor changes, and normal fine tuning and operation after resistor changes.
