[Amps] Questions on Alpha 8410

[Mike & Becca Krzystyniak]

Greetings Thermionic Sages,

    I'm looking at an Alpha 8410 for a friend that is exhibiting what I
consider a weird problem. 

    This amp is 2 weeks old and worked fine until two days ago.
    On SSB, legal limit out in a casual round table, after a little time
transmitting the amp faults and trips out. 
    It resets in about 4-5 seconds and then works for awhile before the same
thing happens.

    The exciter is a FT-1000D. Does this amp need ALC?

    Is there an accessible fault table or software application that read out
the faults and might give a clue?

   Thanks in advance.

PS: On a side note, I know Alpha changed hands but are they still in
business?
