screen supply for Simple PP Pentode mode?

Clearly the question will demonstrates my ignorance of the subject, but here goes:

I'm down to the short strokes on a Simple P/P ( EL84) amp, on which I'm recycling an old pair of Scott LK48 OPT. The last DIY project these were used in was in triode mode - which sounded fine, but I'd like more power this time around. They don't have a U/L tap for screens - what would be a simple way to derive this supply? (at least I knew better than to ask "the best"? :eek: )
