So I finally got around to breadboarding this:
http://sopht.250free.com/low-volume.html
My thought was to just use a 12V wall wart to power the whole kit-n-kaboodle. The heater current for the two tubes comes to 600ma combined. So I put a 1A wall wart on it and figured that should cover it. The problem is that the wall warts aren't really 12V and don't have any regulation in them. I was thinking of a regulator in one of those TO-3 cases that takes 1.5A but I'm really looking for some other simple ideas that I may be missing.
cheers,
