You don't need to take the sock off to properly check the tweeter. Just remove the connector plate and you'll have access to probe the transducer wires directly. It's possible they did this and you didn't notice.
Regardless, as mentioned by Neo, it's possible a quick repair could be implemented on the tweeter. It's fairly easy to bridge a small break in the quasi-ribbon.....if that's all the problem is.

I think it's likely they did remove the plate as you suggest and I wasn't aware of it.
So if there is a break in the wire it will read 0 as they described? I have reason to believe that there is a good chance of wire corrosion (thanks kitty cat)
I think I need to investigate that further.
Thanks
they will also sound better with no sock 'filtering' the HFs. :-))

If there is a break in the transducer, a ohmmeter reading will indicate very high (or infinite) resistance vice around 4 ohms as it should be.
There is also the fuse-holder and various connections in there. I assume those were checked as well.
It's possible the squeeze connectors that are recessed up into the frame cutout might be an issue. It's difficult to probe those directly, so you would normally attach a meter to the wires that lead out from there.
I suspect a removal of the sock would identify the problem fully, but you'd have to remove all those confounded staples at the bottom to do that. :)
Cheers,
Dave.
