I was lucky to obtain this single driver in a gift of 2 very large cabinets containing multiple drivers, and horns. The cabinets were way to large to put to use in my home, and not in very good condition to boot. It was hidden under the mixing bowl in the photos, unfortunately it's companion was a Bozak driver. The 3 crossovers in each cabinet were mis-matched along with most of the drivers and horns. Not sure what the proper terminology is of the mixing bowl covers is, but I'd appreciate some insight on those. What I'm really seeking is info on repairing these Altec's . The cone is in poor condition, and they test at 0 Ohms, so I'm assuming the Voice coils are in need of repair or replacement also. I realize these are special speakers, not really shure on what direction I'll be taking with these. I have several systems at the present, and starting to collect some tube gear. I'd love to repair these myself, but have never repaired a VC. I have no problem paying to have this repaired, as long as they can be restored to the original specs. I'm seeing several kits for this repair but I'm unsure of what is really best for this special speaker. I thank you in advance for any insight anybody can share with me on getting this baby up to spec!
