Unable to find any info on this amp using Google...
What speakers are you trying to drive, and does it match the output of the amp?
I know some Technics amps use a fan to cool them, just woundering if yours has too, and thinking that the fan may be dead, as a result the amp is shutting down to protect it's self.
Worth looking into....
