Onkyo A-803

It is an amp that I had in the early 90s. I 'had good memories. I have therefore bought the same for me in a small group hifi "my hut in the garden." C is true. And, listening, I found the same qualities: strength, musicality, good overall. And .... the same problem that I had forgotten. The source selector changes alone in a more or less rapidly and unexpectedly. It is several days without this problem, then it comes back. And so on. I think I'm not the only one with this concern. Apart from that, it is a quality amp "made in Japan". For me, everything is said.
