Even Rick will tell you to not bother with the parallel output cap. It will likely do more harm than good.

1.414 * the unloaded V of the transformer. Allow for at least 230V here.

The output cap is under spec'd. I am not going to say it again, and I am going to quit this thread. If the tube shorts (because you tapped it, because the cat jumped on the table and bumped it, because the phone rang and you turned your head too fast, because of a power surge, or because it just went bad), the output cap (and possibly your head) will see B+. Generally, a blown cap will not short, but, and this is the important point, it can. Even a short moment of 150V on your head will be unpleasant.
