From the LM324 Datasheet, Page 17, Figure 27: TI shows a square wave oscillator without the pot. In their schematic they show a resistor to the + pin (3,5,10,12 on LM324) from a v+ source. As soon as I connected v+ in this way stage 1 worked like a champ!The reference resistors from TI schematic are 100k. I've only got stage 1 working right now, but going to make the other stages next.
