Firstwatt circuit simulation

I am trying to use a simple online circuit simulator to help me understand the inner workings of the various FW designs. Figured I’d start with a simple design so starting with the F5 and specifically the simplified schematic of the F5 from Nelson’s intro to the design on page 10 here.

Something isn’t quite working right, would appreciate if anyone could help me out. I believe the schematic is editable by others.

Have you considered LTSpice? There’s a lot of LTSpice knowledge here. And there are already some F5 models floating around.
That said, the simplified schematics often lack the detail necessary to actually work. They are more conceptual in nature. Are the output devices in your model even conducting?

I have not found those models and was trying to avoid a learning curve with LTSpice. I’ll have a look but I guess I should be able to get it running on this online tool.
