I was recently given the AL80B with a known AC issue which was found to be
the power supply caps that have been replaced with new CDE caps from
Harbach.  The amp will power up and produce power but about every minute or
so the amp will produce a loud click.  It almost sounds as if someone took
a hammer and hit the case on the amp.  Could this be some kind of HV arc
somewhere in the amp?  Has anyone ever experienced this?  Or possible ideas
of what it could be?
