well I give up on this so I need some help here .
I getting hum from this power amp and I did try shorting the input of both channel and the hum is completely gone , this tell me that the power amp is fine , however my preamp have no hum or only slightly with other power amps . so what is going on ? I can't work this out ,
also when I try to disconnect one of the input then the hum is minimized .
the amp is star earth and each channel got they own separate earth all back to the same central ground point .
Thanks
LT
