Thanks! That's what gave it away to me (and this message is the one I 
incorrected refered to as 'private e-mail' in my last posting to the list.

Err, no. It's 3 NPNs and 2 PNPs. Which makes sense in the 9816 too.

Since I'm going to be using this iufo in a diagram on the HPCC schemaitcs 
CD-ROM in theend, I would be happy to give you a (small) acknowledgement 
for the help you've given if you want it. Just let me know how you want 
me to refer to you.
