Found a few photos.
* inside of the 25 kV can, still attached to the top plate. As you see the rim of the top got quite a bit messy (due to my own inexperience at the time)...
* similar can (for 8 KV) inside (note: this particular version has only one EY51. some have two)
* filling the 8 kV can again with new oil (under vacuum). You can see the flange for the rubber stop in this photo.
According to Philips, the transformer cans were filled under vacuum. It is what I do these days as well, just to be safe.
I'm not certain it is absolutely essential, but I think it is. You might get by with ordinary filling under atmospheric pressure.
I always use new oil. I heat it a bit to make it "thinner".

p.s. it is all an awful lot of work!
