Oops.  Thanks for the correction. Yes, I meant low output impedance.

Hmm.  Well, I still doubt it would matter any what the load is,
because, as you say, the point is to provide a low impedance
signal to the next stage. 

Do you think that maybe the transistor needs a certain amount
of *current* to keep going?  It might happen then that if the
base went down to -4.4V, the current it drew (i.e. over the
1K, about 5.6 milliamps) wouldn't be enough.  But I can't 
remember reading anything like that.

Thanks,
Lee
