Altec 416-?

[timoteus]

I just picked up a second pair of 19s circa 1977. One cabinet has a 416-8B, and the other has the driver in the pic. It has the same frame as the 416-8B and my other 416-8C, the cone is stamped 211844 which I believe is the correct cone for the 416. The only ID marks on the magnet is a square ink stamp that says AL with 64 underneath. I'll assume that means AlNiCo unless somebody corrects me.

I'm trying to figure out what this is. Is it a 416-8B without the cover? A 416-8Z? I'm hoping these two drivers will work together without having to go on the hunt for a new donor driver. I already feel like an idiot for not catching this before the purchase.

Frame is right. Could it be the original motor without the cover? The "AL/64" looks to me like an inspection stamp.

Yeah, looks like a missing motor cover.

Yeah, looks like a missing motor cover.

+1 Looks like a missing motor cover otherwise it should have been stamped 416-8Z that was Altec's designation (Z) for drivers without the motor cover.I would say (416-8B missing cover). I would check the resistance on the driver anyway to make sure it is an 8 ohm driver.

Z models usually had a small sticker or stamped with black ink.

This all sounds very promising. If I have two compatible drivers then I don't have to spend a bunch of money locating a matching driver. They both check out at 6.9ish on my cheapo bouncy meter. If anyone knows where I can get a 416-8B cover with foilcal, please let me know.

That will be a tough one IME.I've never seen one for sale they are just something people don't have or sell. My 19's are 1977 vintage too, and they are 416-8B's I'm almost positive they are 416-8B's minus cover.


Addendum: Rudy Timmerman on eBay makes foil cals special order,you just have to find the cover.
