If you just change the old wax paper caps and the electrolytics (being careful on those to observe polarity!!) you should be OK.
Those little 1-volt filament tubes are delicate. Have you tested them to see if they are OK? Any overvoltage on the filament can burn them out. If you don't have access to a tube tester, you can test the filaments with your ohmmeter for continuity. The pin numbers are on the schematic.
Is your line voltage 240 or what? Check it at the socket with your AC voltmeter. I see from the partial schematic that the set has various taps for different line voltages. I think on a set like this, even if I had a 240 volt mains, I would set the tap at 250. This would lower the voltage a bit coming into the radio for starters, just for a little extra caution. If it plays OK like that, leave it that way as the power supply and tubes would be less stressed.
