It's all good. Ian got back to me shortly after posting my question, so I wasn't left hanging :) The Chaos section works, however I can't get oscillations from the QO side.... All resistors are in their correct little places and all chips are getting power so I have a feeling I may have torched one of the polystyrene caps. I'm trying to put together a large parts order for something I'm trying to build so it will be a couple weeks before I can continue troubleshooting as I don't have any 'styrene caps on hand :( I think I'm going to start using those fancy schmancy multilayer ceramics instead of polystyrene caps in my builds from this moment forth.

Sorry for not getting back to you on that one. Been sick all week. Blech!

Sorry for the confusion.
For R24a and R24b, their cw terminals are connected to J2 (pins 10 and 12).
Their sliders are connected to their ccw terminals and additionally to the cw terminals of R25. These connections are made on the panel, as indicated by the "on pan" label on the schematic.
For S1, the range is low when open (as drawn) and high when shorted.
Hope this is clear now. It might help you to mark the cw and ccw terminals on the panel and to make a little sketch of the wiring before you start soldering. (I think that's what most of us end up doing to keep from getting confused.)
Don't hesitate to ask if you have more questions. I know that my minimalist notation is sometimes confusing to some people.

Ok.... so I'm a bit of a moron, so I have to ask...
How do I wire up R24 (dual ganged QO Fine Tune pot) and S1 (High/Low Range switch)?
For R24, the schematic only shows CW being connected...
For S1, is High when the switch is closed, or is Low when the switch is closed? Or.... does S1a have to be closed and S1b open for high (or vice versa)?
