Hi Andy I blew my 6M Caps one day, but it was 100% my stupidity when I kept bombarding it with a full 100w carrier when I had the amp to go 'online' when it was turned on. This is a firmware setting. It tripped off the first time. I reset it and hit it again (not thinking) and the CAPs blew. I fixed it myself and all I had to do is replace the caps (and repair the board).
I ran mine for years on my remote and made many many mistakes and never had an issue and I tripped it offline a ton of times. In the emails you saw today, you need to ask about the mechanics of the failures first.
