I found this while looking up a 12by7a on google, he has a buncha cool
tube circuits, maybe you guys will get something out of it.....

Some of those designs are relighting my interest in designing a tube booster for my agile modulators to try and see if I can get a few miles of coverage. I think it would be kind of cool to operate a pirate TV station occasionally....

I checked out a few of his circuits, they are pretty good, simple, and he seems to
really know tubes.... On one circuit he says he gets parts from the stuff people
throw away out in the street..... Sounds familiar.....
