Default studiomaster 708 powerhouse amp

anyone know how to diagnose a blown left channel on this amp? there are
no signs of anything burning or frying.


I sit definitely 'blown' or just not working? are all the fuses intact?
If they are intact, check the in/out or insert jack sockets on the
back, they interupt the signal flow to the power amps when a plug is
inserted, bit commonly go intermittent.
