Did you guys ever find a source for any TIL306's?

Jim,

   Yes I finally found a small handfull of 311s at a surplus store. They
may have some 306s but they're about 70 miles from here so I don't get
there very often. I'll try and remember to look for some the next time that
I'm there. Drop me a note in a couple of weeks and remind me. I think I may
have a couple of 306s here but I'm in the midst of cleaning some of the
piles of parts that I've scrounged and pulling parts and re-arranging my
parts cabinents so I can't find them at the moment. What are they used in?
