Hi there. I have a distortion on one side of a A400x. It's and ugly intermittent distortion allowing some music to get through. The distortion does not appear on scope when there is no load - when speaker is connected it appears. Can anyone give me a starting point? Signal seems OK till after preamp section.
Thanks for your patience - I'm learning!

Open emitter resistors (0.33ohm 5W by output transistors.) or less likely, open output transistors.
Thanks for the reply. the resistors measure 0.5 Ohms in circuit - can i check output transistors in circuit?
