That's true..this M&H has that config..but that's not the problem.

Final clue: it is in the damper system..specifically B2..and if you know 
how this particular damper system works, then you have an excellent 
chance of guessing the problem..which I already know..I'm looking for 
the remedy. I have an idea, but I want to see if my colleagues know of 
an easier way than what appears to me to be 'the' solution..
