Yes....all transistor versions so far...? I though today...maybe I heard it
somewhere...5 transistors instead of 3....? Did you say that?  Sometimes
people tell me things and I don't hear it until it becomes my
idea....(that's what my wife sez!) I'll probably try it tonight... be nice
if it works. There is a fet example also, might switch to 3819s ...if it
fixes it. The example is for a 4007 but if you have to go to two ics, why
bother? The dual otas are cheap. (I might try it for fun though)
