Technics SU-V505 amplifier problem
Can anyone suggest an answer -
I have the above Technics amp and I am having problems with the amp cutting off speakers with no apparent reason. No short circuits or overload conditions exist. Speaker relay will drop out and cut off speakers intermittently and will need a restart to clear - sometimes not clearing until after several minutes.
Speakers fitted are wharfdale 6ohm 100W so definitely not lower than the min 4ohm.
Sometimes amp will work for hours and no problem. Sometimes it will cut out after a few minutes or even less.
What is wrong?
