Circuit Help needed for graphic equalizer using LM3915

These are clickable now. Looks like the main differences are the caps used to split the bands.

Band 1 uses a .047 prior to going in to the LM3900 and another .047 that goes around and meets up on the output.
Band 2 uses a .012 before going in and another to the output.
Band 3 uses a .001 prior to going in and a .0022 that goes to the output.

So I wonder if I change the caps to somewhere around .006 for a new band and 2 .024 on the other if that will give me 2 more near the middle. Then I can use 2 of these kits to provide the 5 different bands I need.

Success! Well, so far... I swapped out the caps and it still works! 🙂

I will be doing a full scale test of the LED panel that I made later today and will post images. In the meantime, if you want to see the progress, you can check out my website Reactive Lights | Audio Reactive Lighting Systems

Both of my kids are soldering now, so we are having a good time!
