Thanks for your kind words, I am still a noob but yeah as I've got a little of "already done that" I got some little experience to share and maybe be helpful to someone...

Regarding the voltage pump, what you must consider is the current that you need for the tubes...I guess you should start with a 1MA 12V PS - the heaters want 12V/150mA. The current required at the anodes is much less (around 15-20mA, but here I go guessing, following the tube datasheet).
So from the power input, you'd have one wire going to the heaters and one feeding the voltage pump. I dunno how much current can a voltage pump provide, but I guess it's enough to run a couple of circuits...
Read Rick's experience with the 555 smps - as the circuit needs more current, you have to step down a little with voltage, but hell I guess you can be still quite happy to have 150V and not 200V from that smps...
