I was rather more curious to know where the small signal parameters ended up at. They have not given it.

But the video is very nice to watch, especially for Altec fans. :D

The very beginning shows a picture of the speaker and says 1945 https://hosting.photobucket.com/imag...arev4/1945.jpg

Wonderful! Its right there.... but nobody notices !

I think its around 7/8 years old when a similar situation was reached.
I think it was AB who had observed, " For an Old Guy you have quite sharp eyes !
It still holds water today.:cool:

Thanks

The voice coil used in the restoration seems far too deep. The 515 is an underhung woofer.

Cone and surround are incorrect as well.

That basket is common on later 515b. Stolen pic from wardsweb http://www.wardsweb.org/audio/Altec/515B2.jpg
