That's a polysomething capacitor, so is almost certainly OK. It's the old paper insulated ones, from any manufacturer, that are generally duff by now. Chances are that they're all OK, with the possible exception of any mains filters.

A quick and dirty check on "that capacitor" is to measure the cathode voltage on pin 7 and quickly short the triode anode (pin 9) to chassis. The voltage shouldn't move significantly.
