What caps are you planning on doing, if its working well.

The only caps I generally replace are the coupling caps to the HOT and the 1kv white tube caps think there is one near the damper and the vert circuit.

the vert cap will cause it to be jumpy (vert). I do the HOT cap just because if it goes bad it can damage the flyback.

If you are not having any issues and the cans are not getting very hot, I would leave it be. I have a lot of sets from that era, and often all the cans are just fine.
