I would replace all capacitors...there is probably at the most 20-25 paper caps. If you leave even one in, you run the risk of trouble from it so it is best to replace all. They should be replaced because 1. you will definitely get better performance even if the radio does work and 2. they can short out and damage resistors or coils.
I would not use NOS caps I would use brand new ones.
If there is old wiring with bad insulation where it is difficult to replace it, you can repair it by putting heat shrink tubing over it.
Also you should install a fuse in the power line. You can install an inline fuse holder and put it inside the chassis. 1 1/2 to 2 amps should do.
The thing is that if you really do this throroughly, replace all caps and replace or re-insulate all bad wiring it will work well and not need any work for many years.
