Hypex UcD OEM Kelvin connection (feedback taken at speaker terminals)

Perhaps you can have a discussion with Hypex on how they manage sudden loss of the feedback loop?
I am pretty sure Hypex won't discuss with me regarding an OEM product that were sold indirectly to me, a non OEM. I tried to sign my company up as OEM with Hypex but you really have to be an audio company.
 
When doing experiments like this or other amplifier experiments for that matter, don't connect to expensive loudspeakers.
Noted. I will be using a Mirage who lost its mate. The other one's cabinet glue didn't hold up and it fell from the wall!

There will be a permanently installed medium value resistor between the hot (+) output and the NFB terminal. So, even if the "sense" wire is removed, the amplifier will still be running closed loop and stable.

We had a bunch of Dassault Mirage fighter jets in the 1960s and 70s. They also got cracks in their wing structure and more than a few fell out of the sky...

Well that puts things into perspective. I was upset with Mirage because someone could have been knocked on the head from the falling speaker. They didn't seem to care too much. But certainly a small matter in the world of structural failing.
 
Oh no, I just got the amp modules. They are UcD180-LP not UCD180-OEM. The listing title had the latter but they had used the LP photo so I blame myself for not looking closely (I swear I thought I checked the photo but apparently not). Also, I can't blame the seller too much because Hypex puts glue over the print on the PCB and the coil has a label with UcD180LP OEM. Lots of other sellers of this part are making the same error. I don't see any actual UcD180-OEM for sale so I think this idea is at a dead end and I will just build an amp with these parts.
