Leaky capacitors need replacement?

These need to be replaced, don't they?  

For those who are curious, please take a look at the photo from 6moons.com:

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?

I replaced all the tubes and my amp is still sputtering so next I’m off to a tech to replace those caps and hope that’s the issue.
