Fortunately, if I can't fix it or don't feel like it, I put it in my car and drive to George Meyer AV in LA. They are about four or five miles from my home.
They are authorized repair facilities for so many companies that I have lost count.
Their technicians are very good, friendly and don't mind walking you through what they are doing.
I'm a pretty good electrical engineer and technician, but sometime, well you know.
For example, anyone try to work on a Mark Levinson 23.5? Great, great amp, but a serious PITA to work on. So yeah, George Meyer AV. My Audio Research Gear, same. I let them handle it.
enjoy
