This little fella seems pretty cool but I have some questions. What do I use for a PSU? Could I basically just use a 12v regulated source and a 5000uF cap for filtering?Where does the volume pot go on this thing? Could I have a gain control on this?I've priced out parts and I can get everything minus an enclosure and a speaker for around $50. I'm going to do a lot more reading on tube stuff before setting out to build it, as I always research heavily before getting into a new project.Also, what about biasing the tubes? Hows that work?Yes, I am a tube newb.
