1973 Fender Twin Reverb Speakers cutting out.

That strong rub means that unfortunately they will have to be reconed, even if it weren't for the intermittent problem.
Good news is that they will still work well for another 43 years, so it will be money well spent.

IIRC the terminals are connected to the flex leads via a screw. Make sure that the screw is tight (which isn't easy).

^^^^^^Absolutely! Always tighten those screws when reconing. It's much easier when there's not a cone in the way. The easiest way, if cone is not removed, is to insert a small screwdriver or something of the sort into the wire side and turn it. You can't usually get to the screw head.

Also, keithb7, I gave g1 some info to pass along to you.

What? No "sideways screwdriver?" One of the handiest tools in my kit. Unfortunately no quick link on where to get one, but it's probably a standard item at Harbor Fright. I got mine in a Nagoya hardware store but I'm sure you don't have to go to Japan to find one. Little 90 degree ratchet drive with a bunch of philips & slot & a couple hex heads. Solves a lot of problems!

On assembly DO make sure the metal contact surfaces are freshly scraped clean of all corrosion.

I've had this problem on JBL hi frequency horn drivers too. Bit of a pain to fix but once it's done, good for another 20 years (I hope). And a BIG relief to find I don't have to replace a $$$$$ diaphragm.

Oh, I have a "sideways screwdriver". I just find the method I describe easier to get some torque.

Harbor Freight had them last year. Ace Hardware sells the non ratcheting kind.
