No idea. Diodes in backwards? Transistors in backwards? Missing your main cap? Look for some sort of construction error that you would have repeated.

I ordered these PCBs from Ken Stone in 2013. It comes in a pair of two. I built one with parts that I sourced from mail order. I built the second one from parts that I sourced from Elby Designs, at least a year later. Both units have the same issue. Attack and Decay works fine, although the scope shows the times are rather quick. I can't get the Sustain step to happen. I am using a ±12Volt supply.
Does anyone have a clue?
Thanks,
