5U4 is a stronger tube, but if the 5Z4 is designed in, then it has to be examined if the filament winding has the capacity for the additional 1A of current.
The opposite is OK, if the current capabilities of the 5U4 are not called for.
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.
