Nope.? Works as designed.? Build it and try it.? Picture of my prototype is attached.? You will identify the Set-Reset transistors as a simple transistor version of an RS flip-flop.

I only see one 62R resistor. I assume you mean that one is 68R ??? C10 & C11 are not in the bill of material.

Did you see my other post re the apparent reversal of the 'operate and fault' led's?

The reset switch does not reset the SCR's. Only the astable.
