harry et al:

I tried to reproduce the "saw with teeth missing" on a different op amp, 
and no deal.  It seems to be a weird characteristic of NE5534s.  I 
reproduced the phenomenon on the NE5534.
I don't know.  This square to saw is a major pain in the butt.  It seems 
like the easiest thing would be to run a triangle through a "gate" that 
drops the voltage to zero when it hits a certain reference.  Any ideas on 
a circuit?  

thanks for the input(i'm not done with this yet)

toby
