- The Stonehenge 1 ( 819A ) used the 427-8A tweeter ( which is quite rare ) .

- I see @ one pair a year offered on eBay .

- The closest equivalent ( in JBL parts ) , is the LE20 ( of which there are many on eBay ) .

- The Le25 or LE26 might be made to also physically fit .

- These are all old-style paper-cone tweeters / the Altec model had a metal dustcap ( fwiw ) .

- Parts Express still sell some paper cone type tweeters / what you need to find is a model that gets down to the 1800 hz crossover point .

- Good Luck with your project / those are very attractive cabinets ( certainly worth rehabbing ) !

I heard a pair of Stonehenge II once, not a bad looking cabinet but sound wise it sounded like a B-I-C speaker from the same time period:blink:

Has anyone got or can anyone get access to these measurements for the 427-8a tweeter -
Diameter of the faceplate
Thickness of the faceplate
Diameter of the magnet
Depth of the magnet from the back of the faceplate to the back of the magnet.

Would you like to sell the working Tweeter?
