Remove it, whip out the capacitor across the On-Off switch and then go for it. If it hums loudly and the volume control does not affect this, then the chances are it's faulty. If it hums and the stations sound like they are under water, then the same applies.
The capacitor may be OK on the ESR meter but may be breaking down under load.
There are a load of paper caps underneath the set, Change all these. Especially 'that cap'.
The UL41 may be past it's best - there may be a heater-cathode leak on any of the valves, but the UL41 is the favourite.
