The repair guy from MD was supposedly staying in Toronto and working remotely for the company that now owns Bryston, MD, and Axiom. I do not think the team in the sticks (Dwight, Ontario) know how to repair the MD tuners. I have a MD 108T and I am assuming I need to find a local technician if anything goes wrong. In my area that is not too hard.
I contacted Bryston (James Tanner specifically) to get in touch the MD. He forwarded my email to someone formerly in management at MD. I wanted to get another ST-2 antenna. The guy sounded helpful but then the conversation died.
I have a link somewhere for MD customer support regarding the ST-2 (they replied via some MD support system). I will soon contact customer support via the link to see if they can help.
