I consider balance to be beneficial.
I do provide constructive criticism where I consider it due. You
shouldn't need to dig too deep to find evidence of my having done so.
If I can help with further detail and facts concerning my experience with
the 87A, just let me know.
Some folks I have encountered seem able to break everything they get their
hands on.
We all have experiences; some better than others.
My Alpha 87A ranks among the very best ham radio equipment I have ever
purchased. It is certainly the best amp.
