I'm not sure if this is the right place, but I had my Harman Kardon Amp fixed today by Jez Arkless. He was a pleasure to deal with, asking nothing up front and carrying out quite a few repairs to it in just a couple of hours. What was a very sick amp this morning is now singing happily in my living room this afternoon. I'm well impressed and will undoubtedly use and recommend Jez in future. If I need a phono stage in future, his will be top of my list. Very much appreciated.
