I just wanted to mention another great little Supratek story. Two days ago my Syrah wasn't powering up - it just seemed dead. I emailed Mick and Kevin, and they diagnosed/suggested that my Rectifier tube in the power supply might be dead. They also told me that when this happens it automatically blows a fuse (accessibe easily next to the plug socket) and that there is a spare fuse already there next to the spent fuse.
Sure enough, they were correct, and within mintues I was up and running again just by switching in their already-provided and easily accessed spare fuse, and swapping in another rectifier I had handy. I'm up and running again.
Anyways, not only was the communication swift and accurate, but I was amazed that I didn't even have to figure out what the replacement fuse type was and then go shopping for it. Not sure if this replacement fuse feature is typical, but is struck me as so convenient.
So, long story short, I continue to be a very happy Supratek owner.
