Are those the plug in type out of the Ampex tape recorders? Should be pretty darn good. Relatively low level compared to the Western Electric I just took apart!

fazeka,
no that's not it. although it does look similar. the 2 i have are an inch or so in diameter, stand about 1 1/2 inches tall and have no pins on the bottom. they have a threaded mount on the bottom and the leads come out of this.
