Where's the Kielbasa? The Lutefisk? The Damp Sheep??

But seriously...  I've heard this discussed in and among the Dead  
Horse Graveyard, and since I have a radio apart, now is as good a  
time as any to try it. Just need to pick up the parts in a few days.   
And I need to set up the GPS standard that I've been meaning to for  
the past two years that sits on the shelf pointing and laughing.   
I've got a serious roundtuit deficiency.

Who else has tried the simple DC regulator method and written down  
what the results were versus that of a current regulator?  I'd hate  
to think a team of experienced engineers screwed up something as  
simple as a ballast arrangement.  Maybe if we stepped into our TARDIS  
and took them a boxful of 7812's we could have nipped the whole  
ballast problem in the bud, as Barney Fife would have said?
