So I did some extensive reading on the A10 before buying one recently, but one thing I never found a clear answer on was the cause of the channel failures.
I saw a bunch of people theorise that it was 12V battery boxes killing the input - was that ever confirmed? For people who did have an A10 die, can you comment if you were using 9V or 12V BB's.
I've currently got a 12V BB but if it's going to kill my A10, I'll make a 9V version if it's going to be safer.
