I think the 4mfd cap suggestion is based on the condition when max fully loaded plate to plate AC supply voltage are applied. For "civilian" use, I don't think the tube will break a sweat even when we go over 4mfd. However, what is the limit, I have no idea.
On my preamp, my first cap is 20uf, B+ is 280vdc, my CV717 British version of 5r4 still tested like new after 5 yrs.
