I've got a few questions regarding the 15" fieldcoil that JBL put out briefly in '52. Are there any numbers on how many were actually produced? Does anyone have records as to how much these things have gone for at recent auction?
I've read that the D in the 130s stood for the metal dustcap, but the photos I've seen of the D130E had a paper dustcap, but still a D before the 130...Is there any explanation for this?
Any more specs on this one of a kind creation would be much appreciated. Thanks!
