Housed in a restored 4 room school house, which in its self is a wonder to behold, are countless amazing radio tubes from the last century.
I could go on and on about the function, rarity and unique aspects of the vacuum tubes I saw in the collection, but if tubes are your thing, a visit to the TCA website is the place to go:

Least I say, that the effort of Mr. Sibley in restoring the building (TCA office) and the fantastic display shows a level of dedication seldom seen by mere mortals (me).
