This time ULT's with a broken swivel mount.
It appears this is actually an active recall/repair extended until 2027. I got the part from Alixpress. Damn fiddly to disassemble, the headband wire needs desoldering/soldering but only 13 tiny wires. 😖

Cleaned the PCB and added new 3D printed feet. Nice to have a no repair required PCB for a change.
What's next off the PCB shelf?

Fizz... Pop... Flame... Smoke... 😱
I must admit when I replaced the usual suspect caps I didn't like the look of this. It looked like it had seen better days.
