Thermistor problem in amp


i have a problamatic thermistor in my linn powertek amp!
the amp is fine and sounds fine! BUT when its been on all day or cranked for a bit it shuts off
(not power just sound)
i called linn usa and they said it would cost $250 to get repaired----i asked how much the part is they said $15---
would you advise me to put it in my self--is this an easy job??i am sensible and carefull-----i'll be bugger'd if i'm paying $250
what would you do?????????????
its annoying having ya amp shut down every once in a while--u can turn it off and on again and itll play but in 10 mins its off again--and off till it cools down for a few hrs----
thanx joolz

Most thermistors are mounted directly on top of a transistor or to the heat sink. It might not be a problem to replace, but there could be multiple different thermistors within the circuit. As such, you would have to narrow down which one(s) are defective. Once you've done that, it's simply a matter of properly mounting and soldering it in place.

Sounds simple enough, but if you're working blindly, it might turn into a task. Obviously, Linn seems to think that this is a common problem. As such, they might be willing to point you in the right direction. Sean
