[1000mp] pesky DIN plugs...

Yes.  Power cord on the amp that goes to 240 VAC.
My (old) copy of the NEC suggests that the cord supplied may be used
with up to 18 A.  I am going to try to read the current code (no pun) to
see if something has changed.
    The code is concerned with temp. rise.  We are also concerned with
voltage regulation.  73   Mac  N8TT
