Hi All,
Just checkin' in to see what is up with the loudspeaker world. I have been busy raising kids and every now and then have some free time and might want to build something. As you probably know Dr. Bullock succumbed to lung cancer on February 23, 2004. I really miss him.
I have been collecting drawings of old PA and wooden horn drawings. I am redrawing them in AutoCad to preserve them for the future. If you have any of the classics let me know. I would love drawings of A7's, Karlson Kouplers, Forsythe cabinets, University Classics, K-Horns, La Scala, JBL 4560's, Altec 816, 815, JBL Paragons, 4520, 4520's. You get the idea. I have already done some of them. So if you have some good drawings, scan them and send them on. I would appreciate it.

Hi and welcome.
I have also built horns, check my home page. It was a Schmacks horn and a H. H Klinger horn. The Schmacks horns was the best.

Also condolences about Dr. Bullock. And it is an honor to have you on this forum, Bob.
Yours and Dr. bullock's DOS BoxModel has helped immensely in my understanding about how loudspeakers work.

Jeez, looks like a mod parade here.
Welcome to the forum Bob. I might have some stuff on my HD. I've been collecting interesting stuff for a while, just went thru my 1940s collection of Radio News & Radio Craft & scanned everything of interest. Not many horns in those but i do believe i have the article on Hegeman's Eico design that was his 1st commercial offering.
