Leaky capacitors need replacement?

Is it right that those capacitors have a life rating of 10,000 hours?

Rated 10,000 hours at 105°C, life of a capacitor doubles for every 10 degree Celsius decrease in temperature, that means the capacitor operating life at 55 °C is 320,000 hours!
If a capacitor rated 10,000 hours at 85°C, its operating life at 55 °C is 80,000 hours.

Those two 33uf 350v capacitors are smoothing/filtering purpose, you can clearly see it connected to a 1kohm resistor go to the output tube screen grid.

The + side of the capacitor connected to the 1kohm resistor go to the screen grid(pin 9) of the output tube via a red/orange color wire, can you see it?
