That all looks very normal and in good condition to me.

All those black capacitors look as they should do, but are very likely to be internally electrically leaky. Some of them will be in critical positions and the leakage that they have will likely cause damage to valves and transformers if the mains were applied to the set. Some would advise replacing all of them, although I only tend to replace the ones that are likely to cause problems, as I like to keep with originality as much as possible. The valves will probably all be fine, but you never know and it's a risk you take. Certainly you'd need to check the electrical condition of particularly the output transformer before you start doing a lot of work on the set and also check the continuity of the valve heaters.

You'd need to arrange a 125 volt supply for the set if that's what it's supposed to run off.
