Hmmn, I used to get updates when people posted to this ancient thread, but not any more.
I'm not sure where you're measuring 24VDC at, so it's hard to guess what's wrong. You don't have the LM317s in backwards or something, do you? Did you include the LED? Are you measuring with the tube in the socket? Also, what variety of 2SK117 did you go with? I think you might run into problems if you're using the -Y or -GR versions.
I'm one of those who tried a 1000uf cap for C103, the power reservoir, and one of those who maintains that's undersized. That said, there have been so many variations made of this design, with so many different components, that it's easily possible for pretty much any definitive statement to be disproved...
