Bryston 4Be fault diagnosis, I have one Bryston 4Be doesn't work correctly
Failure phenomena:When the amplifier get warm(maybe 15~30 minutes after power on), The left channel will be issued a "bang" sound noise in every 2~3 minutes.
I've try to disconnect the input-PCB board with non-signal situation. but the noise still on.
So I can confirmed the fault is from the Amplifier-PCB. Bad welding has been excluded.
But which component failure exactly? Is there any tips or experiences can give me?
