Hi,
i'm still restoring that 75 years old radio set.
My first experience with old sets.

Does someone has ever replace all the wires ?

I did replace some wires that lost their insulation, and trace of oxydation was visible. No choice in that case.

It's painfull to unsolder wires that are all tightly wrapped around lugs without breaking the lugs !!!!!

For the rest of the wires, they "might" be good if i avoid moving them.

But what about inside old wires, do they developp intern capacity or lose their conductivity ?

Dry out, they are rigids, and not movable at all, otherwise if i try, the insulation will probably crack.

I suppose a good job is to recabling the whole set.

What do you do in your repairs ?

Repair only what you need to ..wires may be old and brittle..just leave them alone unless insulation is to far gone..In some cases you can use heat shrink where needed...When you start to replace to many wires you might run into the problem of your set not working when all done because of a mis-placed wire...Happens to the best of us

I replace all of the wires in sets containing badly decayed rubber insulated wire, which is a nightmare. I replace the wires with cloth. Others use plastic or medical grade rubber, which hold up well. Cloth is ideal, except in damp conditions, for it doesn't melt or crumble.

When replacing wires, replace one at a time. Cut the wire in the middle, remove one end, connect the new wire, route it exactly as the old wire, remove the other end of the old wire and connect the new wire.

It is really easy to forget where one end goes if you take the whole wire out at once, especially if there is an interruption. If you have to another wire from a terminal to get the one you are replacing loose, put it back immediately or draw a diagram. It only takes one wrong connection to ruin your day.

I'm sure this goes without saying, and was implied in another comment, but if the set is working always check it after EACH replacement. I'm sure some of us have replaced a bunch of caps on a working radio, and then had it not work. Trust me, it's a bi*ch troubleshooting something like that.
Just a friendly reminder.
