Any reason to change ceramic caps? And small transistors and diodes are usually just fine too.
These are 70s, parts were much better. Electrolytics are the only ones I think that should go. Even resistors are usually fine.
Unless it is a piece of mind thing.....


I would recommend against restuffing large electrolytics.
First I don't think they present antique value and with essential parts explicitly replaced with modern the look is gone, nor it is that important. Why restuff Nichicon when it is a Japanese mfr available today with the same name and making better caps?
However the main reason is: this is solid state. They work with MUCH larger currents compared to tube-based.
This is where thermal becomes important.
By restuffing you thermally insulate the cap that might sore!y need that extra cooling by the ambient.
