Altec Build

The front side of the one with the most damage. I could not get to the backside around the surround so had to put the tissue on the froont. I used the Kodak Lens Cleaning paper and the acid-free adhesive shown. The repair seems strong yet flexible.



This is the same repair viewed from the backside.



Not all that pretty but hopefully functional. By the way, for other newbies who might be in the same boat, removing the hold down ring does nothing to the cone. It remains at rest in perfect position.

I might add that I have other speakers and devices drilled similarly around an edge, and I have never before seen anything drilled and machined to such perfection. No matter how you rotate the ring and the cardboard gasket, all holes line up perfectly. It's cliche, but they don't make them like this anymore.

Not Lineco but similar product from BrodArt. And I think I have come up with a great tissue; Kodak lens cleaning paper is at least as thin and light as packing tissue, but maintains its strength when wet making it much easier to work with and position with the wet glue.

Thanks all for your valuable input.

You're welcome! Hope they perform OK, they're very rare now. Best to high pass them above ~350 Hz for testing since your repairs should only affect its HF BW.

OK, thanks, don't recall ever seeing that brand.

Yeah, that probably is a good repair paper, been so long since I've used it, I'd clean forgot about it. Got to digging through a closet and found some in a camera bag, though it's Olympus brand. Makes me wonder if the Minolta SRT101 in it is worth repairing.
