When using larger cap vale in the rectifier filter (the very first cap after the rectifier tube) you will end up with higher rectified voltage. This might make tubes run hotter.
Other caps (after the choke) are indeed not as important.

20A used higher values to compensate for 25Hz. But give it 50Hz and the average voltage goes up.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
