My instinct tells me it's the tube. There may be some loose pieces of
crud floating around inside. Try removing the tube and cycling the amp
on and off a number of times to see if it still arcs.
I had an AL-1200 years ago where the tube blew, but it wasn't
intermittent - it blew in no uncertain terms. Ameritron replaced the
tube under warranty.
