Jimmy, yes, I do realise you are right about all the things you said. Maybe I got stuck here, because I already felt this was the right spot, having contact with several members. Ofcourse I dont think you want me to kick lol.Prob I will try some other threads or make a new one, depending on the progress from my side. I will check that link you gave me. I am not really technical, but I thought that behind the elco's of my PS-5 4x resistors were on the board. behind the left elco two of them became black. I just found a good old fashioned electronics shop here who is willling to check it for me, so I will have no part in reparing it.
