Resimulated the 100% original circuit... it works very well. There is
in the power supply... probably an undocumented "hysteresis" for the
or perhaps some other feedback mechanism...

Most designs have features that make you think that the original
1) Was VERY clever and is doing stuff so subtle YOU don't notice it
2) Was an absolute IDIOT.
I always assume #1 until proven wrong. In this case I dont know if it
