I purchased an used X250 to drive my TAD Horn speaker with impedence 8 ohm and sensitivity 103db one month ago. I found that the X250 stay cool even after running for 8 hours. The heat sinks temp. rise to less than 10 degreeas C above room temp.
Any simple way to check whether I should send my X250 back to local dealer for bias-checking?

No, a regular bias check up is not required, but all our amplifiers
are biased for approximately the same temperature, so anyone
can apply the 5 second temperature test to decide whether
their amp might need to be looked at.
Circuits occasionally fail, and we do run across pieces in the
field that have had their bias potentiometers tweaked by users.
