Flying Mole DAD-M100pro repair

[Moby]

Hey guys, I try to help my friend with this repair. So far PSU filtering caps are dead, all together with PSU mosfets  (2SK2638).
On the back side of the mosfet's  heat sink is "this guy". I presume it's something used for temperature compensation but I have no clue what component it is. It measures approx 60ohm . I would like to check it before I replace Mosfets. Can you identify the component? Or maybe someone got the schematics???

Thanks mate.

It looks like they come in various nominal resistances so try to find circuit documentation to see if 60 ohms is right, and/or get a correct replacement.

Well, documentation from manufacturer wil be tricky since product is still in production. But thanks anyways

You may confirm that it is still functional by measuring resistance with a VOM while heating/cooling it. If it looks like it is working correctly, it could be OK.

I found the working one and guy kindly gave me to measure it. It's 60ohms, so it seems like Ok. Cheers
