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

Take the cover off and try to locate the thermistor. It should be close to the power switch. If it looks like something you can do, then decide for yourself.
