You can put in a bucking transformer to lower the power line voltage and extend the life of the components.
There is no polarity on those paper capacitors. Either way you hook them up they are okay.
I have a Dumont 401R that I'd love to sell. It needs one capacitor, the funny one in the power supply that resonates the power transformer (constant voltage transformer). Otherwise I believe it's fine. Been sitting on the patio for years now and I might just part it out. I have manuals, schematics, etc. and got some good use out of it before I got my Tektronix.
