Oops! I forgot about that.

I made a mistake, the emitter of Q12 should be connected to the base of Q6 instead

The original circuit is shown here. A nice kit is presented here.

Thanks for the link.
To be honest, I tore that circuit apart and made it into a much simpler, basic bare-bone version

While the operation might be identical, there are significant differences in performance between your circuit and the original. Are you aware of what they are?

Speed and accuracy and of course the RC timing calculation will be way off
