As a follow up of all my previous posts, my SA-1 was never fully functional flawlessly since it was returned from Philips Service Center. It wasn't until I finally managed to send the unit to Marantz Japan to get it fixed. Upon return, Marantz included a piece of ribbon cable and a fuze without any notes. I am not sure if Marantz was trying to tell that it was the ribbon cable that was causing all the problem. Now I am a happy chap.
Marantz SA-1 reliability problem
I ran across a few threads regarding SA-1 update on AudioAsylum. I blew a fuse a week ago on this unit. Since the fuse is concealed inside the power supply, replacing it would have voided the warranty. Living in California, I suspect this has something to do with the fluctuating voltage caused by the energy crisis since one of my friend who has the same unit suffered the same problem one month ago. Do any other SA-1 owners have the same problem?
