I just finished my wavebubble and it doesn't work. I'm a little bummed out. I can hear it when it is on is that normal?

Did some more testing and played with the frequencies. It works now, the range just sucks. In the gain stage should I have placed R23 and R24. In the instructions it says to but in the picture it just has bridges.

C46 and C49 in the parts list they are 1uF caps in the instructions they are 0.1uF caps. What should they be? Please these are easy questions help me out.

i used the 0.1uF from teh schematic. the sirenza datasheet recommends the same thing. however, i'm not quite sure because the bubble is using a more dynamic frequency range that isn't quite covered in the datasheet (at least to my quick reading).
