Hi Dan,

Thanks for the substitutions. I am going to try to look for those later. I
chose this design because I liked the idea of a self adjusting, self
resonant oscillator, and it looked like a really simple circuit, but the
component selection may be a little more exotic than I thought. I don't like
designs with exotic components, especially in  things like a Tesla coils,
where active components are expected to blow up on a regular basis! :-).

It also seems that the only place the HC74LS14 is mentioned on the internet
is that particular circuit that I want to build!

Thanks again,
Sue
