When it was suggested that we have a look at the 4CX5000A/8170 constant 
current curves, I had them on the Web within ten minutes.  When are one 
of you DAF enthusiasts going to post the QBL's curves?.  My guess is that 
the QBL curves are quite similar to the 8170 curves.  In other words, the 
QBL's positive grid potential region is quite unlikely to support the DAF 
case.  I bet a large pizza w. salad bar and brewski lunch that the QBL 
curves will not be posted by a DAF true-believer.
