I have 416-8Bs.

One cone is numbered 18035400-01,

the other ?21184?4(smudged)

All I have found so far is in this AK post - http://www.audiokarma.org/forums/sho...t=51943&page=2 which doesn't include the 180 numbers but mentions 35400.


I also have 421-8Hs.

Both have cones stamped 35402.

I wish to know if the cones are legit Altec ones. I can remember seeing an Altec components Table which included later cones that didn't follow the 391 first three number rule but can't locate it now. Any replies are welcome.

Cheers, Marshall.
