muel Posted July 13, 2012 Share Posted July 13, 2012 I really like this receiver! Certainly worth a full recap if you haven't done it! Get it working though... but I'm no help with that. If you don't find the help you need here then Audiokarma has quite a few Yamaha nuts (a compliment) who really know what they are doing. ManyMoonsAudio rebuilt some Yamaha equipment for me... I've been quite happy with his work. Quote Link to comment Share on other sites More sharing options...
