I'm avoiding it now! My KPA1500 died for the second time since it
arrived last September. I contacted service last Thursday and, per
request, sent them my configuration information. Nothing has been heard
since.
Now my "old" KPA500 and KPA500 are back in line and working fine! That
appears to be a good fix as they've never let me down.

Eric -
I know a number of KPA1500s have been returned to you with one of the
output transistors dead. Is there common source for the problem that
the rest of us can try and avoid?

Hi Peter,
I'm sorry to hear about this failure and deeply apologize for the
problem.
I'll follow up with another email to you to diagnose what actually
happened.
In any case we'll deal with it quickly and get your amp repaired asap.
