Wow. I didn't see the  msg that preceded this, but should I assume 
that the "MP" should always be run at full output, even while driving 
(in my case) an Alpha 87A? My amp only requires about 40-50 w. Maybe 
that explains some problems I've had with the units.

Incidentally, why shouldn't the MP be run at reduced power? What is 
the function  of that power control then? What am I missing?

If the answer is "yes" - what external attenuator is recommended?

Thanx Chaps - - -
