Dating Astatic Mics.

Astatic has no information concerning the serial numbers or the dates of mics, but we can, with a little detective work get some approximations. The first clue is that the element had a date stamp in the early models. In other cases we have actual purchase dates for a small number of mics from eBay. We know that Astatic moved to Conneaut, Ohio from Youngstown before 1946. Rivets on the label is also a clue to age. Astatic stopped using labels in the 80's and stamped the side of the shell with JT-30. Then stopped using any marks at all.
