Submini Tube Power Supply

I am ready to make a power supply to power up my submini tubes for a project/testing. I just ordered a toriodal tranny (the EH type from digi-key 12v wallwart in, 160VDC out). All the examples of apps for these trannys do not show how to get the 6.3 filament voltage. Does anybody have an idea or a rough schematic?

click ON...

if I`d wanted to power up 6V tubes, I`d use a 6...9V AC wallwart...
(maybe a lowdrop reg...),
or would think about wether I was going to use 2 identical tubes...

If I change the value of the wall wart the output, which is based on the tranny ratio, will give me a much lower B+. I need at least 160VDC. I was thinking that I'd use a voltage divider but not sure how the whole power supply's schematic should look.
Thank you for the links.

i think it`s all in there - somewhere (link ON...)
