Yes, I figured it out almost immediately that there must be a short if component leads are in the same channel.
Now the LED pairs are working perfectly in series.
Sorry. I made a mistake in the lower left schematic.
For a cutoff frequency of 4.9Hz then R9 is 100k like the schematic above it.
For its gain to be 3 then R8 is 300k.
The datasheet shows that the outputs are the collector of an NPN transistor so they never go high unless you add a pullup resistor.
The outputs are constant current sinks that never go low unless you add a resistor in series with an LED.
Then the output will be a low when the LED turns on.
The datasheet shows that the first LED has a small current in it for cascading ICs when it is supposed to be turned off. It shows adding a 20k resistor across the LED so that it does not dimly glow.
